In addition, your symptoms may not be related to how weak your heart is; you may have many symptoms but your heart function may be only mildly weakened. Or you may have a more severely damaged heart but have few symptoms. How is heart failure diagnosed? To diagnose heart failure, ...
2004). Surviving adult hesr2-null mice, which otherwise exhibit a mildly disturbed phenotype, also displays decreased LVFS (Sakata et al. 2002; unpublished data). Together, these observations suggest that cardiomyocyte anomalies in hesr2-null mutant mice lead to decreased LV systolic function. View...
approximate the anterior and posterior mitral leaflets, has been shown to reduce death and HF hospitalization in carefully selected patients with symptomatic HF despite optimal medical management and moderate to severe or severe mitral regurgitation with preserved LV size (end-systolic dimension...
HF with mildly reduced EF (HFmrEF) LVEF of 41%-49% Evidence of spontaneous/provokable increased LV filling pressures (eg, elevated natriuretic peptide, noninvasive and invasive hemodynamic measurement) HF with preserved EF (HFpEF) LVEF ≥50% Evidence of spontaneous/provokable increased LV filling...
Right ventricular enlargement is common in the advanced stages, and the heart size is increased in the craniocaudal diameter, with increased sternal contact. 6. As the condition progresses, the pulmonary veins entering the left atrium become congested and enlarged. 7. The pulmonary veins are larger...
Subjects were divided into 3 groups depending on their relative heart volumes (RHVs): (1) very enlarged heart group (VEHG; male, n = 1251; female, n = 201), with RHVs of greater than 14 (male) and 13 (female) mL/kg; (2) mildly enlarged heart group (MEHG; male, n = 702; ...

左主冠状动脉压迫综合征(LMCS)是由主动脉和增大的肺动脉干之间的左主冠状血管(LMCA)压迫引起的一种具有良好特征的现象。LMCS的发展通常在严重肺动脉高压的背景下描述。在非配对先天性心脏病(CHD)的背景下,LMCS病例是挑战传统治疗模式的复...
Full size image As shown above, the homeostatic HRV responder could have a good predictive and simulation performance for many HRV time series. Notably, the estimated parameters may be inconsistent if the stability coefficient is close to 1. In this case, the parameter value can be approximated ...
Atrial size is an important factor in determining how a patient responds to treatment for the disease. For instance, it is more difficult to achieve and maintain a normal rhythm in patients with enlarged atria. Transesophageal echocardiography (TEE): It is a special echocardiographic technique that...
