drug eluting stent☆Everolimus and its pharmacologic counterparts (eg, sirolimus, zotarolimus) are cytostatic drugs that inhibit mTOR (mammalian target of rapamycin receptor), blocking the cell cycle between the G1 and S phase to reduce smooth muscle cell proliferation.
Coating the intracoronary stent surface with an antiproliferative agent such as everolimus creates a drug-eluting stent that helps ☆prevent neointimal hyperplasia and stent restenosis. cardiologypharmacologyUWorld SIM2 Jun 20, 2020, 9:37 PM HirotoShishido

下壁梗塞においては時に迷走神経トーヌスが過剰に亢進することがあり,Bezold―Jarisch reflexとして知られる。迷走神経が緊張すると消化管の蠕動運動は亢進し,高じれば悪心や嘔吐,下痢などの消化器症状を呈することとなる。実際には下壁梗塞の約半数に消化器症状が認められるとする報告もある。 cardiology卒試国試 Oct 20, 2020, 1:25 AM HirotoShishido

the strongest risk factor for coronary heart diseasehighest→ ☆diabetes mellitus, noncoronary atherosclerotic disease, CKD
other major risk factors→ HTN, hyperlipidemia, smoking, ↑age, obesity, physical inactivity
Several studies have shown that diabetes mellitus is one of the strongest risk factors for coronary heart disease.
The risk of dying from coronary heart disease exceeds the risk of dying from any of the other listed causes, even in the absence of other major risk factors forcoronary heart disease. cardiologyUWorld Jun 27, 2020, 5:35 AM HirotoShishido

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 cardiologyUWorld SIM2 Jun 21, 2020, 6:42 AM HirotoShishido
