Genetically elevated gamma-glutamyltransferase and Alzheimer's disease
2018
Observational epidemiological evidence supports a linear and independent association between serum gamma-glutamyltransferase (GGT) concentrations and the risk of Alzheimer's disease (AD). However, the causality of this association has not been previously investigated. We sought to assess the causal nature of this association using a Mendelian randomization (MR) approach. Using inverse-variance weighted MR analysis, we assessed the association between GGT and AD using summary statistics for single nucleotide polymorphism (SNP)-AD associations obtained from the International Genomics of Alzheimer's Project of 17,008 individuals with AD and 37,154 controls. We used 26 SNPs significantly associ…
The electrocardiographic ‘triangular QRS-ST-T waveform’ pattern : a marker of severe haemodynamic compromise in Takotsubo syndrome : a case report
2020
Abstract Background Takotsubo cardiomyopathy is characterized by transient regional systolic dysfunction of the left ventricle, mimicking myocardial infarction. Although systolic left ventricular (LV) function normalizes in most cases, the outcome is not always favourable. Recently, a rare electrocardiogram (ECG) finding, lambda wave ST elevation or ‘triangular QRS-ST-T waveform’, was suggested as a possible marker of poor outcome in Takotsubo patients Case summary After a brief episode of chest pain and shortness of breath, a 67-year-old woman developed cardiogenic shock. Her resting ECG showed widespread ST elevations, which soon evolved into a pattern of triangular QRS-ST-T waveforms in …
Handgrip strength is inversely associated with fatal cardiovascular and all-cause mortality events
2020
Purpose: We aimed to assess the associations of handgrip strength (HS) with cardiovascular and all-cause mortality and whether adding data on HS to cardiovascular disease (CVD) risk factors is associated with improvement in CVD mortality prediction.

Cross-Country Skiing and Running’s Association with Cardiovascular Events and All-Cause Mortality:A Review of the Evidence
2019
A large body of evidence demonstrates positive, graded effects of PA on cardiovascular disease (CVD) morbidity and mortality with increasing intensity compared with lower PA intensity. Running is often designated as a high-intensity PA with substantial evidence supporting its health benefits. Cross-country skiing is among the most demanding aerobic endurance exercises and requires engaging the upper- and lower-body. Cross-country skiing is often regarded as high-intensity PA, which has been associated with significant health benefits. However, a robust body of evidence identifying the dose-response relation between cross-country skiing volume and health outcomes is sparse. Therefore, this r…

Is sauna bathing protective of sudden cardiac death? A review of the evidence
2019
Sudden cardiac death (SCD) is a global public health burden accounting for 15–20% of all deaths. Though established atherosclerotic risk factors explain a large proportion of the risk of SCD, these factors are often absent in a large proportion of SCD victims and the pathogenesis of SCD is still not fully established. It therefore appears that additional factors may be involved. Sauna bathing is a traditional Finnish activity that is mainly used for the purposes of relaxation and pleasure. Beyond its use for these purposes, sauna bathing has been linked with several health benefits. Emerging evidence suggests that sauna bathing is associated with reduced risk of adverse cardiovascular (CV) …
Is low cardiorespiratory fitness a feature of metabolic syndrome in children and adults?
2022
Objectives Cardiorespiratory fitness (CRF) has been inversely associated with risk of cardiometabolic diseases. However, there are no studies comparing the independent associations of CRF scaled by body size and composition using different approaches with cardiometabolic risk factors between children and adults. We therefore investigated these associations in children and adults using same measures for CRF and cardiometabolic risk factors. Design Cross-sectional. Methods A total of 352 children (47.2 % girls) and 572 men were included in the study. Peak oxygen uptake (V̇O2peak) was measured during a maximal exercise test on a cycle ergometer and was scaled by total body mass (BM−1), total f…
Physical activity and risk of venous thromboembolism: systematic review and meta-analysis of prospective cohort studies

Extracellular vesicles and high‐density lipoproteins: Exercise and oestrogen‐responsive small RNA carriers
2023
Decreased systemic oestrogen levels (i.e., menopause) affect metabolic health. However, the detailed mechanisms underlying this process remain unclear. Both oestrogens and exercise have been shown to improve metabolic health, which may be partly mediated by circulating microRNA (c-miR) signalling. In recent years, extracellular vesicles (EV) have increased interest in the field of tissue crosstalk. However, in many studies on EV-carried miRs, the co-isolation of high-density lipoprotein (HDL) particles with EVs has not been considered, potentially affecting the results. Here, we demonstrate that EV and HDL particles have distinct small RNA (sRNA) content, including both host and nonhost sRN…

Cardiovascular and Other Health Benefits of Sauna Bathing:A Review of the Evidence
2018
Sauna bathing, an activity that has been a tradition in Finland for thousands of years and mainly used for the purposes of pleasure and relaxation, is becoming increasingly popular in many other populations. Emerging evidence suggests that beyond its use for pleasure, sauna bathing may be linked to several health benefits, which include reduction in the risk of vascular diseases such as high blood pressure, cardiovascular disease, and neurocognitive diseases; nonvascular conditions such as pulmonary diseases; mortality; as well as amelioration of conditions such as arthritis, headache, and flu. The beneficial effects of sauna bathing on these outcomes have been linked to its effect on circu…

Sports and exercise medicine clinic in public hospital settings: A real-life concept and experiences of the treatment of the first 1151 patients
2022
AbstractExercise has been shown to have a multitude of health-promoting effects, including improvements in cardiorespiratory and muscular fitness, function, symptoms and risk factors. Furthermore, exercise may slow down, stop or even reverse the progression of various non-communicable diseases (NCDs). Despite the overwhelming evidence, exercise is still not comprehensively used as a treatment component either in primary care or in hospital settings. The outpatient Sports and Exercise Medicine Clinic (SEMC) is the first specialized clinic in Finland to use exercise as part of patient protocols in the public health care system. Patients needing specialist attention due to NCDs, usually combin…
Combined Effect of Sauna Bathing and Cardiorespiratory Fitness on the Risk of Sudden Cardiac Deaths in Caucasian Men: A Long-term Prospective Cohort …
2018
Both cardiorespiratory fitness (CRF) and frequency of sauna bathing (FSB) are each strongly and independently associated with sudden cardiac death (SCD) risk. However, the combined effect of CRF and FSB on SCD risk has not been previously investigated. We evaluated the joint impact of CRF and FSB on the risk of SCD in the Kuopio Ischemic Heart Disease prospective cohort study of 2291 men aged 42-61 years at recruitment. Objectively measured CRF and self-reported sauna bathing habits were assessed at baseline. CRF was categorized as low and high (median cutoffs) and FSB as low and high (defined as ≤2 and 3-7 sessions/week respectively). Multivariable adjusted hazard ratios (HRs) with confide…

Should inflammatory pathways be targeted for the prevention and treatment of hypertension?
2019
Hypertension is the most common modifiable risk factor for cardiovascular disease (CVD)1 and is a leading cause of death globally.2 Hypertension and CVD share common antecedent risk factors which include physical inactivity, obesity and excess alcohol intake.3 Though these established risk factors explain a large proportion of hypertension risk, its pathogenesis is still not fully established as it appears that other additional lifestyle and genetic factors may be involved. There is therefore a need to identify and evaluate putative risk factors that may increase our knowledge of hypertension development, may have causal or predictive relevance, and which will help develop preventive and ma…
Running away from cardiovascular disease at the right speed: The impact of aerobic physical activity and cardiorespiratory fitness on cardiovascular …
2020
Higher levels of physical activity (PA) and cardiorespiratory fitness (CRF) are associated with lower risk of incident cardiovascular disease (CVD). However, the relationship of aerobic PA and CRF with risk of atherosclerotic CVD outcomes and heart failure (HF) seem to be distinct. Furthermore, recent studies have raised concerns of potential toxicity associated with extreme levels of aerobic exercise, with higher levels of coronary artery calcium and incident atrial fibrillation noted among individuals with very high PA levels. In contrast, the relationship between PA levels and measures of left ventricular structure and function and risk of HF is more linear. Thus, personalizing exercise …
Joint effect of blood pressure and C-reactive protein and the risk of sudden cardiac death : a prospective cohort study
2020
Background Both blood pressure and C-reactive protein (CRP) are each independently related to mortality risk. However, the combined effect of systolic blood pressure (SBP) and CRP on sudden cardiac death (SCD) risk has not been studied. Patients and methods We studied the joint impact of SBP and CRP and the risk of SCD in the Kuopio Ischemic Heart Disease prospective cohort study of 1953 men aged 42–61 years with no history of ischemic heart disease. Baseline investigations were conducted between March 1984 and December 1989. SBP and CRP were measured. SBP was divided based on median values to low and high (median cutoffs 132 mmHg) and CRP as low and high (median cut-off 1.30 mg/L). Hazard …

Exercise cardiac power and the risk of heart failure in men: A population-based follow-up study.
2019
Little is known about exercise cardiac power (ECP), defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise, on heart failure (HF) risk. We examined the association of ECP and the risk of HF.This was a population-based cohort study of 2351 men from eastern Finland. The average time to follow-up was 25 years. Participants participated at baseline in an exercise stress test. A total of 313 cases of HF occurred.Men with low ECP (9.84 mL/mmHg, the lowest quartile) had a 2.37-fold (95% confidence interval (95%CI): 1.68-3.35, p0.0001) hazards ratio of HF as compared with men with high ECP (13.92 mL/mmHg, the highest quartile), after adjust…
Relative peak exercise oxygen pulse is related to sudden cardiac death, cardiovascular and all-cause mortality in middle-aged men
2018
Background Preliminary evidence suggests that peak exercise oxygen pulse – peak oxygen uptake/heart rate-, a variable obtained during maximal cardiopulmonary exercise testing and a surrogate of stroke volume, is a predictor of mortality. We aimed to assess the associations of peak exercise oxygen pulse with sudden cardiac death, fatal coronary heart disease and cardiovascular disease and all-cause mortality. Design A prospective study. Methods Peak exercise oxygen pulse was assessed in a maximal cycling test at baseline in 2227 middle-aged men of the Kuopio Ischaemic Heart Disease cohort study using expired gas variables and electrocardiograms. Relative peak exercise oxygen pulse was obtain…
Identification of Gut Microbial Lysine and Histidine Degradation and CYP-Dependent Metabolites as Biomarkers of Fatty Liver Disease
2023
Numerous studies have described specific metabolites as biomarkers ofsevere liver diseases, but very few have measured gut microbiota (GM)-produced metab-olites in fatty liver disease. We aimed atfinding GM signatures and metabolite markersin plasma and feces related to high liver fat content. Based on imaging, we dividedstudy participants into low (,5%, LF,n= 25) and high (.5%, HF,n= 39) liver fatgroups. Fecal (LFn= 14, HFn= 25) and plasma (LFn= 11, HFn= 7) metabolomes ofsubsets of participants were studied using liquid chromatography/high resolution massspectrometry. The GM were analyzed using 16S rRNA gene sequencing. Additionally,blood clinical variables and diet were studied. Dyslipide…
Prognostic Relevance of Cardiorespiratory Fitness as Assessed by Submaximal Exercise Testing for All-Cause Mortality: A UK Biobank Prospective Study
2020
Objective: To investigate if the inverse associations of cardiorespiratory fitness (CRF) with all-cause and cardiovascular mortality in the general population vary among individuals who are at different pre-test risk. Patients and Methods: CRF was assessed through submaximal bike tests in 58,892 participants aged 40-69 years who completed baseline questionnaires between January 1, 2006 and December 31, 2010 in the UK Biobank study. Participants were categorized into risk categories, which determined allocation to an individualized bike protocol. These were “minimal risk (1)”, “small risk (2)” and “medium risk (3)” groups (i.e., those who cycled at 50%, 35% of predicted maximal workload and …
Physical activity and risk of atrial fibrillation in the general population : meta-analysis of 23 cohort studies involving about 2 million participan…
2021
Regular physical activity is well established to be associated with reduced risk of cardiovascular disease outcomes. Whether physical activity is associated with the future risk of atrial fibrillation (AF) remains a controversy. Using a systematic review and meta-analysis of published observational cohort studies in general populations with at least one-year of follow-up, we aimed to evaluate the association between regular physical activity and the risk of AF. Relevant studies were sought from inception until October 2020 in MEDLINE, Embase, Web of Science, and manual search of relevant articles. Extracted relative risks (RRs) with 95% confidence intervals (CIs) for the maximum versus the …

Pulmonary embolism location is associated with the co-existence of the deep venous thrombosis.
2019
Multiple studies have shown that in approximately half of individuals with pulmonary embolism (PE), the deep venous thrombosis (DVT) is not evident at the moment of PE diagnosis. The underlying factors and the origin of PE in these patients are not completely understood: missed DVT, embolization of DVT in its entirety, or de-novo PE being possible explanations. The aim of this study was to evaluate the differences in PE patient with or without co-existing DVT. Sixty-three consecutive PE patients were included. Whole leg bilateral Doppler compression ultrasound was performed to all patients. The PE location and extension, C-reactive protein, platelet count, hemostatic markers FV, FVIII, FXII…
Associations of cardiorespiratory fitness, body composition, and blood pressure with arterial stiffness in adolescent, young adult, and middle-aged w…
2022
AbstractFew studies have investigated whether higher cardiorespiratory fitness (CRF) or favourable body composition are related to lower arterial stiffness in women. We therefore investigated the associations of CRF, body fat percentage (BF%), fat free mass index (FFMI), and mean arterial pressure (MAP) with arterial stiffness in 146 women aged 16–58 years. CRF was assessed by a maximal exercise test with respiratory gas analysis either on a cycle ergometer or a treadmill. Aortic pulse wave velocity (PWVao), augmentation index (AIx%), and MAP were assessed by a non-invasive oscillometric device and BF% and FFMI by a bioelectrical impedance or DXA device. CRF was inversely associated with PW…
Exercise-based cardiac rehabilitation
2020
Abstract Exercise-based cardiac rehabilitation (CR) is well-documented and justified integral part of disease management in stable coronary heart disease patients. CR programs are defined as multifactorial and comprehensive, with physical activity counseling and exercise training as key components in all rehabilitation and preventive interventions. The physiological and clinical benefits of exercise-based CR are widely established with similar benefits for women and men and advanced aged patients as well. In patients with cardiovascular disease, exercise-based CR elicits favorable effects on the cardiac function, endothelium and skeletal muscle resulting to an improvement of quality of life…
Endocrine effects of sauna bath
2020
Abstract Sauna bath brings about numerous acute changes in hormone levels, partly akin to other stressful situations, partly specific for sauna. Norepinephrine increases in those accustomed to sauna bath. Sweating increases the production of antidiuretic hormone, and the renin–angiotensin system becomes activated. Of the anterior pituitary hormones, growth hormone (GH) and prolactin (PRL) secretion is increased. Also β-endorphin has been frequently reported to increase, whereas the responses of antidiuretic hormone and cortisol are variable, probably depending on the type of sauna exposure. Sperm production decreases in particular in sauna-naive men, but reduced fertility has not been assoc…
Longitudinal associations of physical activity, sedentary time, and cardiorespiratory fitness with arterial health in children – the PANIC study
2021
We investigated the longitudinal associations of physical activity (PA), sedentary time (ST), and cardiorespiratory fitness (CRF) with arterial health among children. In our primary analyses, we investigated 245 children (girls 51.8%) aged 6-9 years participating in the baseline examinations who had data on arterial health at 2-year follow-up. We also utilized a subsample of 90 children who had a complete arterial health data at baseline and 2-year follow-up. ST (≤1.5 METs), light PA (>1.5-4 METs), moderate PA (>4-7 METs), vigorous PA (>7METs), and moderate-to-vigorous PA (MVPA, >4 METs) were assessed by combined movement and heart rate monitoring and CRF by maximal exercise testing on a cy…
Exercise, Sports & Cardiovascular Health: Relevant Questions and Answers
2019
Introduction Currently, it is quite common for a clinical cardiologist to be questioned about exercise and sports, topics that are rarely discussed during formal medical education. In this regard, there is a clear need to access high-quality data and evidence-based information to give patients and family members the best advice. Aiming to present the state-of-the art scientific information on the topic, we have invited several experts from different countries, all of them “knowledge-producers” in exercise and sports cardiology, to contribute [...]
Lipoprotein(a) is not associated with venous thromboembolism risk.
2020
Objectives. Evidence from case-control studies as well as meta-analyses of these study designs suggest elevated lipoprotein(a) [Lp(a)] to be associated with an increased risk of venous thromboembolism (VTE). Prospective evidence on the association is limited, uncertain, and could be attributed to regression dilution bias. We aimed to assess the prospective association of Lp(a) with risk of VTE and correct for regression dilution. Design. We related plasma Lp(a) concentrations to the incidence of VTE in 2,180 men of the Kuopio Ischemic Heart Disease cohort study. Hazard ratios (HRs) (95% confidence intervals [CI]) were assessed and repeat measurements of Lp(a) at 4 and 11 years from baseline…

Sauna exposure leads to improved arterial compliance: Findings from a non-randomised experimental study.
2017
Background Heat therapy has been suggested to improve cardiovascular function. However, the effects of hot sauna exposure on arterial compliance and the dynamics of blood flow and pressure have not been well documented. Thus, we investigated the short-term effects of sauna bathing on arterial stiffness and haemodynamics. Design The design was an experimental non-randomised study. Methods There were 102 asymptomatic participants (mean age, 51.9 years) who had at least one cardiovascular risk factor. Participants were exposed to a single sauna session (duration: 30 min; temperature: 73℃; humidity: 10–20%). Pulse wave velocity, augmentation index, heart rate, blood pressure, mean arterial pres…
Impact of Cardiorespiratory Fitness on Survival in Men with Low Socioeconomic Status
2020
Abstract Aims Although both low socioeconomic status (SES) and poor cardiorespiratory fitness (CRF) are associated with increased chronic disease and heightened mortality, it remains unclear whether moderate-to-high levels of CRF are associated with survival benefits in low SES populations. This study evaluated the hypothesis that SES and CRF predict all-cause mortality and cardiovascular disease mortality and that moderate-to-high levels of CRF may attenuate the association between low SES and increased mortality. Methods This study included 2368 men, who were followed in the Kuopio Ischaemic Heart Disease Study cohort. CRF was directly measured by peak oxygen uptake during progressive exe…
Acute Hemodynamic Responses to Combined Exercise and Sauna.
2020
AbstractThis study investigated acute hemodynamic, plasma volume and immunological responses to four loading protocols: sauna only, and sauna after endurance, strength or combined endurance and strength exercise. Twenty-seven healthy, slightly prehypertensive men (age 32.7±6.9 years) were measured at PRE, MID (after exercise), POST, POST30min and POST24h. The measurements consisted systolic and diastolic blood pressure, heart rate, body temperature and concentrations of high-sensitive C-reactive protein, white blood cells and plasma volume measurements. Endurance+sauna showed significant decreases in systolic blood pressure at POST (–8.9 mmHg), POST30min (–11.0 mmHg) and POST24h (–4.6 mmHg)…
P640Sex differences in cardiovascular and all-cause mortality in middle-aged and older participants of a medically-supervised exercise program
2019
Abstract Background Physical inactivity has been shown to be associated with all-cause mortality in both healthy and unhealthy middle-aged and older individuals. While regular exercise is equally recommended for men and women, it is virtually unknown if sex influences the long-term survival among participants of a medically-supervised exercise program (MSEP). Purpose To evaluate if cardiovascular and all-cause mortality differs between men and women who participates in a MSEP. Methods Retrospective data from an open cohort of individuals aged 36 to 85 years old (66% men) who participated in a private MSEP between March 1994 and December 2018 were analyzed. The participants were free to atte…
The Duke treadmill score with bicycle ergometer: Exercise capacity is the most important predictor of cardiovascular mortality
2018
Background The Duke treadmill score, a widely used treadmill testing tool, is a weighted index combining exercise time or capacity, maximum ST-segment deviation and exercise-induced angina. No previous studies have investigated whether the Duke treadmill score and its individual components based on bicycle exercise testing predict cardiovascular death. Design Two populations with a standard bicycle testing were used: 3936 patients referred for exercise testing (2371 men, age 56 ± 13 years) from the Finnish Cardiovascular Study (FINCAVAS) and a population-based sample of 2683 men (age 53 ± 5.1 years) from the Kuopio Ischaemic Heart Disease study (KIHD). Methods Cox regression was applied for…
Silencing of C3G increases cardiomyocyte survival inhibition and apoptosis via regulation of p-ERK1/2 and Bax.
2018
Experimental studies have shown that overexpression of Rap guanine nucleotide exchange factor 1 (C3G) plays pro-survival and anti-apoptotic roles through molecule phosphorylated extracellular signal-regulated kinase1/2 (p-ERK1/2) in cardiomyocytes. However, it is still unclear if silencing of C3G may increase cell survival inhibition and apoptosis in cardiomyocytes, and whether C3G silence induced injuries are reduced by the overexpression of C3G through regulation of p-ERK1/2 and pro-apoptotic molecule Bax. In this study, the rat-derived H9C2 cardiomyocytes were infected with C3G small hairpin RNA interference recombinant lentiviruses, which silenced the endogenous C3G expression in the ca…
Marriage Dissatisfaction and the Risk of Sudden Cardiac Death Among Men
2018
Conflicts in marriage have been associated with potential risk of cardiovascular disease; however, there is lack of prospective evidence on the association between marriage satisfaction and sudden cardiac death (SCD). We aimed to assess the association between perceived level of marriage satisfaction and risk of SCD. This study employed the Kuopio Ischemic Heart Disease study, an ongoing prospective population-based study in Finland. Perceived level of marriage satisfaction was assessed in 2,262 men using a well-structured self-administered questionnaire. Multivariable adjusted Cox regression models were used to estimate hazard ratios (95% confidence interval [CI]) for SCD. During a median …
Cardiorespiratory Fitness and the Risk of Serious Ventricular Arrhythmias: A Prospective Cohort Study.
2019
Cardiorespiratory fitness (CRF) is an established risk factor for cardiovascular disease outcomes. However, the relationship of CRF with risk of ventricular arrhythmias (VAs) is unknown. We aimed to assess the prospective association of CRF with the risk of serious VAs. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2299 middle-aged men in the Kuopio Ischemic Heart Disease prospective cohort. We corrected for within-person variability in CRF levels using data from repeated measurements 11 years apart. During median follow-up of 25.3 years (interquartile range, 18.7-27.2 years), 73 serious VAs were recorded. The age-…

Overweight and obesity are associated with cardiac adverse structure remodeling in Chinese elderly with hypertension
2019
AbstractThere is limited information on the association of overweight and obesity with cardiac remodeling in elderly population. Therefore, we investigated whether overweight and obesity are associated with cardiac geometric structures and function in Chinese elderly. A total of 1183 hospitalized patients (aged 65–99 years) with primary hypertension were collected retrospectively in a cross-sectional study, and divided into underweight, normal weight, overweight and obesity patient groups according to their body mass index (BMI). Cardiac echocardiographic parameters were compared between the groups. BMI was 17.2 ± 1.2, 21.4 ± 1.2, 25.1 ± 1.2, 30.2 ± 2.6 kg/m2 in underweight, normal weight, …
Association between ideal cardiovascular health and risk of sudden cardiac death and all-cause mortality among middle-aged men in Finland
2021
Background Strong associations have been demonstrated between the American Heart Association’s cardiovascular health (CVH) metrics and various cardiovascular outcomes, but the association with sudden cardiac death (SCD) is uncertain. We examined the associations between these CVH metrics and the risks of SCD and all-cause mortality among men in Finland. Methods and results We used the prospective population-based Kuopio Ischaemic Heart Disease cohort study, which consists of men between 42 and 60 years of age at baseline. CVH metrics were computed for 2577 men with CVH scores at baseline ranging from 0 to 7, categorized into CVH scores of 0–2 (poor), 3–4 (intermediate) and 5–7 (ideal). Mult…
Temporal changes in personal activity intelligence and mortality : data from the aerobics center longitudinal study
2021
Background Personal activity intelligence (PAI) is a metric developed to simplify a physically active lifestyle for the participants. Regardless of following today's advice for physical activity, a PAI score ≥100 per week at baseline, an increase in PAI score, and a sustained high PAI score over time were found to delay premature cardiovascular disease (CVD) and all-cause mortality in a large population of Norwegians. However, the association between long-term temporal change in PAI and mortality in other populations have not been investigated. Objective To test whether temporal change in PAI is associated with CVD and all-cause mortality in a large population from the United States. Method…

Underweight and obesity are related to higher mortality in patients undergoing coronary angiography: The KARDIO invasive cardiology register study
2022
Background: In patients with some cardiovascular disease conditions, slightly elevated body mass index (BMI) is associated with a lower mortality risk (termed “obesity paradox”). It is uncertain, however, if this obesity paradox exists in patients who have had invasive cardiology procedures. We evaluated the association between BMI and mortality in patients who underwent coronary angiography. Methods: We utilised the KARDIO registry, which comprised data on demographics, prevalent diseases, risk factors, coronary angiographies, and interventions on 42,636 patients. BMI was categorised based on WHO cut-offs or transformed using P-splines. Hazard ratios (HRs) with 95% confidence intervals (CI…
