Exercise training can reduce rehospitalization rate and mortality in patients with chronic heart failure (CHF).Current exercise training of CHF patients is usually traditional continuous moderate and low intensity aero-bic training.In recent years,more and more evidence indicated that high intensity aerobic interval training (HIIT) possessed more significant effects on CHF patients.The present article made a short review on research progress of HIIT in CHF patients.

Sudden cardiac death (SCD)is the most serious complication of hypertrophic cardiomyopathy (HCM). Although its annual incidence rate is about 1%,but its risk rises year by year.In HCM treatment,identifying high risk patients of sudden death and implantable cardioverter defibrillator (ICD)implantation becomes a feasible meas-ure to save life.The present review mainly summarized risk factors for SCD in HCM patients,analyzed current somewhat conflicting relative guidelines,and temped to provide data for most rational clinical decision.

Objective:To explore influence of plan-do-check-act cycle (PDCA)nursing on mental state and quality of life (QOL)in patients with myocardial infarction during hospitalization.Methods:A total of 90 patients with acute myocardial infarction treated in our hospital were selected.According to nursing method,they were divided into PDCA nursing group (n=45)and routine nursing group (n=45).Mental state and QOL during hospitalization were compared between two groups.Results:Compared with before nursing and routine nursing group after nursing,after nursing,there were significant reductions in scores of self-rating anxiety scale [(60.31 ±4.56)scores,(56.45 ± 4.46)scores vs.(35.64±5.43)scores]and self-rating depression sale [(67.41±4.56)scores,(59.35±4.32)scores vs.(32.54±4.23)scores]in PDCA nursing group,P <0.01 all;compared with routine nursing group after nurs-ing,there was significant reduction in onset times of angina pectoris per day [(3.09±1.10)times/d vs. (1.24± 0.39)times/d]during hospitalization,significant rise in six dimension scores and total score of QOL [(53.75 ± 15.34)scores vs.(71.17±24.3)scores],and satisfaction (86.7% vs.97.8%)in PDCA nursing group,P <0.05 or<0.01. Conclusion:PDCA nursing can improve mental state and quality of life in patients with myocardial infarc-tion during hospitalization.
