[Exercise therapy for heart failure].

In chronic heart failure of CAD, therapeutic approach will be available either with drugs or exercise. With exercise, coronary risk factors such as BP, lipid, DM and obesity will be controlled. In addition, ischemia will also be controlled by decreasing oxygen demand related to BP and HR, and with increasing oxygen supply by increased ECNOS gene expression, collateral formation and regression of coronary stenosis. Infarct size is also reported to be decreased by increasing MnSOD in the cell by exercise. Prognosis of CHF is also good in various evidence of exercise therapy. Recent advances of molecular biology have revealed various mechanisms of exercise effect. Thus, exercise if properly prescribed without provoking ischemia will be basically and clinically effective therapy for patients with CHF.

Gitelman's syndrome with exercise-induced ventricular tachycardia.

A 62-year-old female with palpitations was admitted to hospital where she recorded 12,299 monofocal ventricular premature contractions (VPCs) in 24 h and nonsustained ventricular tachycardia (VT) on exertion. She had hypokalemia with renal potassium wasting, a chloride-resistant metabolic alkalosis, elevated plasma renin, elevated plasma aldosterone (relative to the serum K concentration), hypomagnesemia with renal magnesium wasting, decreased urine calcium excretion, and normal blood pressure. The hypokalemia and hypomagnesemia were thought to have precipitated the VT. The coronary angiogram showed normal coronary arteries; however, the left ventriculogram revealed akinesis of the posterolateral wall. Because the VT could not be induced by programmed electrical stimulation either before or during intravenous administration of isoproterenol, the VPC with the same QRS morphology as the VT became the target of radiofrequency catheter ablation (RF-CA). Intracardiac mapping showed that the earliest activation site was situated in the asynergic area of the left ventricle (LV) and radiofrequency catheter ablation directed at the LV asynergy area completely eliminated the VPCs without any complications. During the follow-up period (6 months), she was free from palpitation and VT was not clinically documented.
