Elevated B-type natriuretic peptide in asymptomatic men with chronic aortic regurgitation and preserved left ventricular systolic function.

Serum B-type natriuretic peptide (BNP) levels reflect myocardial strain and are known to be elevated in patients with heart failure. To determine if BNP levels are elevated in patients with aortic regurgitation, we measured BNP levels in patients with chronic asymptomatic aortic regurgitation and normal left ventricular systolic function.

Imaging and diagnostic testing: diastolic dysfunction after coronary artery bypass grafting: a frequent finding of clinical significance not influenced by intravenous calcium.

Background: Diastolic dysfunction is common immediately after coronary artery bypass surgery (CABG). The duration of this phenomenon is unknown. Intravenous calcium is frequently administered during separation from cardiopulmonary bypass (CPB).
