Does intraaortic balloon counterpulsation improve right ventricular failure resulting from pressure overload?
In a model of right heart failure, the institution of intraaortic balloon counterpulsation caused a significant improvement in cardiac function. Although RV ischemia was not demonstrated, the augmentation of left coronary artery blood flow by intraaortic balloon counterpulsation and subsequent improvement in left ventricular function suggest that left ventricular ischemia contributes to RV dysfunction, presumably through a ventricular interdependence mechanism. Therefore, study of the safety and efficacy of intraaortic balloon counterpulsation in the management of patients with acute right heart dysfunction is warranted.
Our findings suggest that the sources and types of carbohydrates were differentially associated with metabolic syndrome according to sex in the Korean adult population. The percentage of energy from carbohydrates in men and intake of refined grains, including white rice, in women were associated with metabolic syndrome.
