Different calculations of ankle-brachial index and their impact on cardiovascular risk prediction.
2008
Background— An ankle-brachial index (ABI; ratio of ankle and brachial systolic blood pressure) <0.9 indicates peripheral arterial disease (PAD) and is a strong predictor of cardiovascular events. The aim of the present study was to address the prognostic value of different methods of ABI calculation. Methods and Results— In 831 patients admitted with chest pain for diagnostic heart catheterization, blood pressure of both anterior and posterior tibial arteries was measured. ABI was calculated for each leg with the higher of the 2 ankle pressures (current definition of the American Heart Association) or with the lower of the 2 ankle pressures (modified definition) in relation to the highe…
Non-invasive peripheral vascular function, incident cardiovascular disease, and mortality in the general population
2021
AIMS Evidence suggests that peripheral vascular function is related to cardiovascular disease (CVD) and mortality. We evaluated the associations of noninvasive measures of flow-mediated dilatation and peripheral arterial tonometry with incident CVD and mortality. METHODS AND RESULTS In a post-hoc analysis of the community-based Gutenberg Health Study, median age 55 years (25th/75th percentile 46/65) and 49.5% women, we measured brachial artery flow-mediated dilatation (N = 12,599) and fingertip peripheral arterial tonometry (N = 11,125). After a follow-up of up to 11.7 years, we observed 595 incident CVD events, 106 cardiac deaths, and 860 deaths in total. Survival curves showed decreased e…
Heat shock protein 70 in patients with chronic heart failure: relation to disease severity and survival
2004
Heat shock protein 70 (Hsp70) is essential for cellular recovery, survival and maintenance of cellular function. Research into the possible use of Hsp70 as a cytoprotective therapeutic agent is ongoing. Chronic heart failure (CHF) is a state associated with systemic inflammation, particularly in patients with cardiac cachexia. We hypothesised that circulating Hsp70 levels are elevated in patients with CHF, more so in cachechtic patients, and that Hsp70 levels would relate to mortality.We studied 107 patients (28 female, age 67+/-1 years, NYHA class 2.6+/-0.6 and LVEF 29+/-1%, mean+/-SEM) and 21 controls. Cardiac cachexia was present in 32 patients. Hsp70 was detectable in 41% of CHF patient…
Tumor Marker Carbohydrate Antigen 125 Predicts Adverse Outcome After Transcatheter Aortic Valve Implantation
2013
ObjectivesThis study sought to predict the value of tumor marker carbohydrate antigen 125 (CA125) before and after transcatheter aortic valve implantation (TAVI) for all-cause death and a composite endpoint of death, admission for heart failure, myocardial infarction, and stroke (major adverse cardiac events [MACE]).BackgroundRisk stratification after TAVI remains challenging. The use of biomarkers in this setting represents an unmet need.MethodsCA125 was measured in 228 patients before and after TAVI. The association with outcomes was assessed using parametric Cox regression and joint modeling for baseline and longitudinal analyses, respectively. CA125 was evaluated as logarithm transforma…
Cardiopulmonary Hemodynamic Profile Predicts Mortality After Transcatheter Tricuspid Valve Repair in Chronic Heart Failure.
2020
This study was designed to assess hemodynamic changes in response to transcatheter tricuspid valve edge-to-edge repair (TTVR) and to identify hemodynamic predictors associated with mortality.Severe tricuspid regurgitation (TR) is associated with high mortality. TTVR effectively alleviates heart failure symptoms, but comprehensive hemodynamic characterization of patients undergoing TTVR is currently lacking.This international, multicenter study included 236 patients undergoing TTVR. Data from clinical assessment, echocardiography, intraprocedural right heart catheterization, and noninvasive cardiac output measurement were analyzed. Hemodynamic predictors for mortality were identified using l…
Randomized comparison between the invasive and conservative strategies in comorbid elderly patients with non-ST elevation myocardial infarction.
2016
Abstract Background Comorbid elderly patients with non-ST-elevation myocardial infarction (non-STEMI) are underrepresented in randomized trials and undergo fewer cardiac catheterizations according to registries. Our aim was to compare the conservative and invasive strategies in these patients. Methods Randomized multicenter study, including 106 patients (January 2012–March 2014) with non-STEMI, over 70 years and with comorbidities defined by at least two of the following: peripheral artery disease, cerebral vascular disease, dementia, chronic pulmonary disease, chronic renal failure or anemia. Patients were randomized to invasive (routine coronary angiogram, n = 52) or conservative (coronar…
Physical activity may not be associated with long-term risk of dementia and Alzheimer's disease.
2020
Background: While it is well established that physical activity is associated with reduced risk of vascular and non-vascular outcomes as well as mortality, evidence on the association between physical activity and dementia is inconsistent. We aimed to assess the associations of physical activity with the risk of dementia and Alzheimer’s disease (AD).Material and methods: We analysed data on 2,394 apparently healthy men with good baseline cognitive function from the prospective population-based Kuopio Ischaemic Heart Disease study. We assessed habits of physical activity at baseline using a 12-month leisure-time physical activity (LTPA) questionnaire. Using Cox regression, we calculated haza…
Non-alcoholic fatty liver disease increases the risk of incident chronic kidney disease
2020
BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease. Its role in the development of extrahepatic co-morbidities is under investigation. The impact of NAFLD on the development of chronic kidney disease (CKD) is incompletely understood. The aim of this study was to explore the potential contribution of NAFLD on CKD in Germany. METHODS: The Disease Analyzer Database covering 7.49 million cases in Germany was explored for patients diagnosed with NAFLD between 2000 and 2015 and was matched 1:1 to a cohort without NAFLD. Matching criteria included age, sex, physician, index year and co-diagnoses associated with CKD. The primary outcomes of thi…
Plasma Acylcarnitines and Risk of Type 2 Diabetes in a Mediterranean Population at High Cardiovascular Risk
2019
[Context] The potential associations between acylcarnitine profiles and incidence of type 2 diabetes (T2D) and whether acylcarnitines can be used to improve diabetes prediction remain unclear.
Energy Balance and Risk of Mortality in Spanish Older Adults
2021
Clinical data on the direct health effects of energy deficit or surplus beyond its impact on body weight are scarce. We aimed to assess the association with all-cause, cardiovascular and cancer mortality of (1) sustained energy deficit or surplus, calculated according to each individual’s en-ergy intake (EI) and theoretical energy expenditure (TEE), and (2) mid-term change in total EI in a prospective study. In 7119 participants in the PREDIMED Study (PREvención con DIeta MEDi-terránea) with a mean age of 67 years, energy intake was derived from a 137-item food frequency questionnaire. TEE was calculated as a function of age, sex, height, body weight and physical ac-tivity. The main exposur…
