Abstract

Factors in the middle age that are associated with the risk for development of diastolic dysfunction in long term are not fully established. The Oulu Project Elucidating Risk of Atherosclerosis OPERA study randomly selected middle-aged subjects with hypertension and age- and gender-matched control subjects (n = 1,045, age 51 ± 6 years, men 49.8%). After >20 years of follow-up, majority of the subjects still alive were available for reexaminations (n = 600). After excluding the subjects with mitral regurgitation, left ventricular ejection fraction <50%, and those from whom echocardiographic septal E/E' could not be reliably measured, the present analysis included 460 subjects. E/E' was divided into 3 subgroups (subgroup 1: E/E' ≤8, subgroup 2: 8 < E/E' < 15, subgroup 3: E/E' ≥15), subgroup 3 suggesting a significant diastolic dysfunction. Several baseline variables were associated with diastolic dysfunction: greater age (p = 0.001), female gender (p = 0.001), shorter height (p <0.001), larger body mass index (p = 0.008), greater systolic blood pressure (p = 0.001), greater pulse pressure (p <0.001), lower baroreflex sensitivity (p = 0.007), lower estimated glomerular filtration rate (p = 0.02), greater atrial natriuretic peptide...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
