Identification of acute myocardial infarction in elderly patients using optimized highly sensitive troponin I thresholds

2019

Purpose: Established diagnostic thresholds for high-sensitivity cardiac troponins (hs-cTn) might not apply for elderly patients as they are elevated irrespective of the presence of an acute myocardial infarction (AMI). Aim of the present study was to investigate hs-cTnI in elderly patients with suspected AMI and to calculate optimized diagnostic cutoffs. Material and methods: Data from a prospective multi-centre study and from a second independent prospective single-centre cohort study were analysed. A number of 2903 patients were eligible for further analysis. Patients > 70 years were classified as elderly. hs-cTnI was measured upon admission. Results: Around 34.7% of 2903 patients were…

Prognostic usefulness of white blood cell count on admission and one-year outcome in patients with non-ST-segment elevation acute chest pain.

2006

Little is known about the prognostic value of leukocyte count on admission for patients with chest pain. In total, 1,461 patients who presented to the emergency department with non–ST-segment elevation chest pain were studied by clinical history, electrocardiography, serial troponin I determination, and leukocyte count on admission. End points were 1-year mortality and major events (mortality or infarction). Overall patient distribution by quartiles of leukocyte count showed increased mortality (6%, 7%, 6%, and 17%, p = 0.0001) and major events (13%, 13%, 15%, and 24%, p = 0.0001) in the fourth quartile. After adjustment for other risk factors, the fourth quartile cut-off value (>10,000 cel…

Atrial Fibrillation Manifestations Risk Factors and Sex Differences in a Population-Based Cohort (From the Gutenberg Health Study)

2018

Sex differences in cardiovascular risk factors, cardiac structure and function, and disease and symptom burden in the common arrhythmia atrial fibrillation (AF) have not been investigated systematically at the population level. Cross-sectional data of 14,796 subjects (age range 35 to 74 years, 50.5% men) from the population-based Gutenberg Health Study were examined to show the distribution of cardiovascular risk factors by AF status and sex, and to determine sex-specific predictors for AF. The prevalence of AF was higher in men (4.3%) than in women (1.9%). Men had a worse cardiovascular risk factor profile, a higher prevalence of cardiovascular disease, but fewer symptoms than women. Age-a…

Reperfusion therapy for ST elevation acute myocardial infarction 2010/2011:current status in 37 ESC countries

2014

Item does not contain fulltext AIMS: Primary percutaneous coronary intervention (PPCI) is the preferred reperfusion therapy in ST-elevation myocardial infarction (STEMI). We conducted this study to evaluate the contemporary status on the use and type of reperfusion therapy in patients admitted with STEMI in the European Society of Cardiology (ESC) member countries. METHODS AND RESULTS: A cross-sectional descriptive study based on aggregated country-level data on the use of reperfusion therapy in patients admitted with STEMI during 2010 or 2011. Thirty-seven ESC countries were able to provide data from existing national or regional registries. In countries where no such registries exist, dat…

Serum irisin levels, precocious myocardial infarction, and healthy exceptional longevity.

2014

Abstract Background Skeletal muscles produce irisin. Growing controversy exists on the association between this myokine and chronic disease risk. On the basis of the potential protective effects that irisin could exert on both vascular function and skeletal muscle mass, we hypothesized that an elevated level of this molecule may contribute to successful aging. Methods Serum irisin levels were measured using enzyme-linked immunosorbent assay in disease-free centenarians, young healthy controls, and patients with precocious acute myocardial infarction. Results We found the highest levels of serum irisin in disease-free centenarians (35.3 ± 5.5 ng/mL) compared with young healthy controls (20.7…

Genetic variation of the interleukin-1 family and nongenetic factors determining the interleukin-1 receptor antagonist phenotypes.

2009

The natural anti-inflammatory protein interleukin-1 receptor antagonist (IL-1Ra) inhibits the activity of IL-1 and is associated with vascular injury and metabolic disorders. We analyzed genetic and nongenetic determinants of the IL-1Ra phenotype. Fifteen haplotype-tagging single nucleotide polymorphisms (SNPs) in the IL-1α (IL1A), IL-1β (IL1B), and IL-1 receptor antagonist (IL-1RN) genes were determined in the Health 2000 survey (n = 6771) and European myocardial infarction (MI) survivors (n = 972). Three SNPs were genotyped in the FINRISK97 (FR97) study (n = 7222). We found 3 IL1RN variants that were associated with the IL-1Ra phenotype in the study populations and remained significant af…

Morbidity in 565 Type 2 Diabetic Patients According to Stage of Nephropathy

1998

Between 1988 and 1992, 565 type 2 diabetic patients were examined for nephropathy and diabetes-associated diseases during hospital treatment. Stages of nephropathy were defined as no clinical sign of nephropathy (N = 280), microalbuminuria (N = 38), overt proteinuria (N = 105), impaired renal function (N = 55), and chronic dialysis therapy (N = 87). In dialyzed patients, HbA1c averaged 6.8%, and, in the other groups, HbA1c was between 7.6% and 8.3% (normal range, 3.8%-6.1%). Cataract was not associated with the severity of nephropathy. Stroke was most common in the stage of renal insufficiency (34%). The following complications, as found in medical history or as current event, showed a sign…

In-hospital complications of acute myocardial infarction in hypertensive subjects

2005

Recent studies have shown a worse in-hospital outcome in hypertensive than in normotensive patients with acute myocardial infarction (AMI), which has been attributed to more frequent complications. The aim of this study was to investigate clinical patterns, risk factors, and in-hospital complications in hypertensive and normotensive patients with AMI.Of 4994 consecutive patients with AMI admitted to the intensive care unit, hypertensive patients with first infarction (n = 915; mean age 68.8 +/- 11.4 years) and 915 gender- and age-matched normotensive subjects were retrospectively studied.In the univariate analysis, hypertensive subjects presented more frequently non-Q-wave infarction and ST…

Prognostic significance of repetitive ventricular response in chronic coronary artery disease.

1985

A prospective study was conducted in 267 patients with angiographically defined coronary artery disease without documented ventricular tachycardia to determine the prognostic significance of repetitive ventricular response (RVR) after programmed electrical stimulation (PES). The patients were classified inducible if RVR with 3 or more echo beats (RVR greater than or equal to 3) could be induced. 89 patients without previous myocardial infarction (MI), 61 survivors of MI occurring between 6 weeks and 3 months before and 117 patients who had survived longer than 3 months after MI were studied. A standardized stimulation protocol with single (S1S2) and double (S1S2S3) extrastimuli during ventr…
