Carvedilol: A Promising Drug Combined with Lipid-lowering Medications for Patients with Hypertension and Heart Failure

Background: Statins frequently cause myopathy especially in combination with fibrates, and physical activity is considered a trigger for the muscle disorder. Elevated plasma levels of creatine kinase (CK), lactate dehydrogenase (LDH) and aldolase, are the main indicators of the severity of myopathy. Carvedilol is commonly used with lipid-lowering drugs in the management of heart failure, hypert...

Stress echocardiography in heart failure

Echocardiography has the ability to noninvasively explore hemodynamic variables during pharmacologic or exercise stress test in patients with heart failure. In this review, we detail some important potential applications of stress echocardiography in patients with heart failure. In patients with coronary artery disease and chronic LV dysfunction, dobutamine stress echocardiography is able to di...

Antioxidant treatment attenuates pulmonary arterial hypertension-induced heart failure.

ROS have been implicated in the development of pathological ventricular hypertrophy and the ensuing contractile dysfunction. Using the rat monocrotaline (MCT) model of pulmonary arterial hypertension (PAH), we recently reported oxidative stress in the failing right ventricle (RV) with no such stress in the left ventricle of the same hearts. We used the antioxidant EUK-134 to assess the role of ...

Measurement of pulmonary arterial elastance in patients with systolic heart failure using Doppler echocardiography

OBJECTIVE A reliable and easy-to-perform method for measuring right ventricular (RV) afterload is desirable when scheduling patients with systolic heart failure to undergo heart transplantation. The present study aimed to investigate the accuracy of echocardiographically-derived pulmonary arterial elastance as a measurement of pulmonary vascular resistance by comparing it with invasive measures...
