the most important intervention to lower the risk of myocardial infarction
☆smoking cessation
・cigarrete smoke generates free radicals that oxidaze LDL and accelerate atherosclerosis
・nicotine causes catecholamine release, resulting in α1 mediated vasoconstriction
・arteriolar wall damage induces endothelial cell dysfunction and consequently, prostacycline and nitric oxide production decrease

cardiac glycosides
mechanism,adverse effects
digoxin
direct inhibition of Na+/K+ATPase
indirect inhibition of Na+/Ca2+ exchanger
→↑[Ca2+]i→positive inotropy
stimulates vagus nerve→↓HR

the third heart sound(S3)
the fourth heart sound(S4)
S3 early diastole(can be normal in children,trained athlete,pregnancy)
→sign of volume overload
S4 late diastole→consider abnormal including pressure overload,severe hypertension
