Acute effects on the ventricular function in Swedish snuffers: an echocardiographic study.

abstract：BACKGROUND:Many patients with pulmonary hypertension (PH) have symptoms of angina without evidence of occlusive coronary artery disease. For the first time, this study addresses the influence of progressively increasing pulmonary artery pressure (PAP) on left anterior descending artery flow in a rat model of PH. The ro...
