Temporal trends in percutaneous coronary intervention outcomes among older patients in the United States.

abstract：:The aortocaval fistula is a classic model of pure cardiac volume overload in rats. This model is characterized by dilation of the ventricular cavities and eccentric cardiac hypertrophy. There are also changes in peripheral arterial flow: high flow in the proximal part of the aorta, upstream of the shunt, and low flow ...
