Improvement of left ventricular ejection fraction, heart failure symptoms and prognosis after revascularization in patients with chronic coronary artery disease and viable myocardium detected by dobutamine stress echocardiography

Abstract

Patients with substantial viability on DSE demonstrated improvement in LVEF and NYHA functional class after revascularization; viability was also associated with a favorable prognosis after revascularization.

Clinical effects of enhanced external counterpulsation treatment in patients with ischemic heart failure

“…It could be easier to understand why EECP therapy resulted in a significant improvement in functional capacity if it would be given attention of its effect on the circulation. Previous studies showed that improvement in NYHA class has been associated with a favorable prognosis (22,23). It has been shown that EECP treatment improved symptoms and functional capacity in patients with or without systolic HF (19)(20)(21) therapy (25).…”

Wearable Cardioverter-Defibrillator Therapy for the Prevention of Sudden Cardiac Death

“…For example, partial or complete recovery of LVEF has been observed in more than half of patients at 3 months after AMI after institution of heart failure therapies or revascularization. [15][16][17][18][19][20] Guideline-directed medical therapy with β-blockade and renin-angiotensin-aldosterone system antagonism during the early period after diagnosis of nonischemic cardiomyopathy may result in improved ventricular function and decreased future risk of SCD; 50% of patients with newly diagnosed nonischemic cardiomyopathy will demonstrate a 10% improvement in LVEF with the initiation of medical therapy. 21,22 Although the rationale and reasons for postponing ICD implantation are sensible, the current evidence base is incomplete.…”

Can late gadolinium enhancement by cardiovascular magnetic resonance identify coronary artery disease as the etiology of new onset congestive heart failure?

“…Discerning the etiology of LV dysfunction is often the first step in management. Underlying coronary artery disease (CAD) and ischemia are responsible for approximately two-thirds of all systolic dysfunction [1] and delineating it from nonischemic causes has essential therapeutic [2,3,4] and prognostic [5,6,7,8] implications. The electrocardiogram (ECG) [9], presence of anginal chest pain [10], and elevated troponins [11] are unable to accurately differentiate ischemic from nonischemic cardiomyopathy (NICM).…”
