Remote Ischemic Conditioning Improves Cardiovascular Function in Heart Failure Patients.

Background: Recently, it has been shown that remote ischemic conditioning (RIC) can be used as a healthy regimen to reverse disease and aging. With this in mind, we are studying the consequences of RIC on cardiovascular function in heart failure patients.

Methods: Forty patients with stable heart failure were prospectively enlisted and randomly divided into RIC (n = 20) and control (n = 20) groups.

Ventricular fibrillation during coronary angiography in a patient with left dominant coronary artery ectasia.

The presence of coronary ectasias in otherwise normal epicardial coronary arteries are an infrequent angiographic finding. Coronary ectasia is not a benign condition and has been associated with a high risk of coronary events. In the present case, a patient with left dominant coronary artery ectasia who developed ventricular fibrillation during coronary angiography is described.

Reciprocal changes in 12-lead electrocardiography can predict left main coronary artery lesion in patients with acute myocardial infarction.

Acute left main coronary artery (LMCA) occlusion may result in acute myocardial infarction (AMI) or sudden death. ST elevation in the aVR and V1 leads is reported to be valuable in recognizing LMCA occlusion. Early recognition of electrocardiogram (ECG) changes, such as reciprocal ST depression in other leads, is helpful in averting this disaster.

Myocardial and peripheral concentrations of beta-endorphin before and following myocardial ischemia and reperfusion during coronary angioplasty.

There is substantial evidence indicating that endogenous opioid peptides are involved in the pathophysiology of myocardial ischemia and reperfusion. We measured the myocardial and peripheral concentrations of beta-endorphin before and following myocardial ischemia and reperfusion during coronary angioplasty. The results indicate that in patients with coronary artery disease, there was an augmented myocardial concentration of beta-endorphin.
