Effects of + Gz acceleration on cardiovascular system

Objective To overview the effects of various modes of + Gz exposure on morphology,metabolism and function of the cardiovascular system and to understand in-depth the potential damage of + Gz exposure to the cardiovascular system.Literature resource and selection Searched the Pubmed and Wanfang database,collected the literature about + Gz and cardiovascular.Literature quotation Forty-seven published papers were cited.Literature synthesis The epidemiology of cardiovascular diseases of the pilots,such as myocardial ischemia and arrhythmias was overviewed.And the emphasis was put on the research progress of + Gz impact the on the cardiac structure,function,metabolism,etc.Conclusion High +Gz is the risk factor of cardiovascular disease.According to the overviews of +Gz impact on the cardiovascular system,the protective measures are proposed to ensure flight safety and to improve combat effectiveness.
