This study aimed to evaluate the long-term clinical outcomes of patients with acute myocardial infarction (AMI) who underwent successful stent implantation and were subsequently treated angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB). Among 13104 enrolled in Korean AMI registry, 2763 elderly aged 70 years older, prescribed either ACEI ARB at discharge, included this study. Propensity score matching (PSM) was performed adjust for baseline confounders....

Abstract Background Ventricular-arterial coupling (VAC) plays a crucial role in the initiation and progression of heart failure patients with coronary artery disease. The influence VAC on left ventricular (LV) function may vary depending LV systolic function. This study investigated relationship between acute myocardial infarction (AMI), stratified by ejection fraction (EF). Methods Echocardiographic indices volumes, function, diastolic were measured using standard techniques. Effective...

Type 2 diabetic patients have increased cancer risk. We developed and validated an all-site risk score in a prospective cohort of 7374 Chinese type free known history at enrolment, using split-half validation. Spline Cox model was used to detect common factors guide linear transformation non-linear factors. After median follow-up period 5.45 years, 365 (4.95%) cancer.

Increased plasma glucose concentration is a predictive factor for mortality in both diabetic and non-diabetic subjects. Although glycated haemoglobin (HbA1c) useful index of mean blood concentrations over the preceding 1 to 3 months, there are few data regarding its relationship cardiovascular risk. We have examined between HbA1c risk factors 1280 subjects with normal tolerance. Based on tertiles (tertile 1: n = 427, 262 men 165 women, level: 2.9–4.7 % 3.2–4.2 women; tertile 2: 426, 261...
