The strain relaxation index (SRI), a novel diastolic functional parameter derived from tagged magnetic resonance imaging (MRI), is used to assess myocardial deformation during left ventricular relaxation. We investigated whether diastolic function indexed by SRI predicts heart failure (HF) and atrial fibrillation (AF) over an 8-year follow-up. As a part ...

In chronic ischemic heart disease (IHD), focal stenosis, diffuse atherosclerotic narrowings (DAN) and microcirculatory dysfunction (MCD) contribute to limit myocardial flow. The prevalence of these IHD levels in fractional flow reserve (FFR) interrogated vessels remains largely unknown. Using intracoronary measurements, 91 coronaries (78 patients) with intermediate stenoses were classified in ...

Little is known about how atrial oxygen supply responds to increased demand, and under which conditions it falls short (supply/demand mismatch). Here, we have investigated the vasodilator response, oxygen extraction and lactate production of the left atrium (LA) and left ventricle (LV) in response to atrial pacing and atrial fibrillation ...

To determine if an integrated health care system is selective and consistent in the use of angiography, as reflected by normal coronary rates. Rates of normal coronary arteries with elective coronary angiography vary considerably among U.S. community hospitals. This variation may in part reflect incentives in fee-for-service care. Using national ...

Background-Patients with heart failure (HF) are typically designated as having reduced or preserved ejection fraction (HFREF, HFPEF) because of the importance of left ventricular ejection fraction (LVEF) on therapeutic decisions and prognosis. Such designations are not necessarily static, yet few data exist to describe the natural history of LVEF over ...

Most patients at low to intermediate risk for an acute coronary syndrome (ACS) receive a 12- to 24-hour "rule out." Recently, trials have found that a coronary computed tomographic angiography-based strategy is more efficient. If stress testing were performed within the same time frame as coronary computed tomographic angiography, the ...

Phosphatidylserine is translocated from the inner to the outer leaflet of the plasma membrane in the early stages of apoptosis and necrosis and in reversibly injured cells. In rabbit hearts, ischemia followed by reperfusion results in exposure of phosphatidylserine on myocytes unaffected by apoptosis or necrosis. Lactadherin was recently introduced ...

Benign prostatic hyperplasia is a frequent disease among elderly, and is responsible for considerable disability. Benign prostatic hyperplasia can be clinically significant due to lower urinary tract symptoms that take place because the gland is enlarged and obstructs urine flow. Transurethral resection of the prostate remains the gold standard treatment ...
