Management of ST-segment-elevation myocardial infarction during the coronavirus disease 2019 (COVID-19) outbreak: Iranian"247" National Committee's position paper on primary percutaneous coronary intervention.

World Health Organization has designated coronavirus disease 2019 (COVID-19) as a pandemic. During the past several weeks, a considerable burden has been imposed on the Iranian's healthcare system. The present document reviewed the latest evidence and expert opinion regarding the management of ST-segment-elevation myocardial infarction during the outbreak of COVID-19 and outlines a practical algorithm for it.

ICAM-1 polymorphisms (G241R, K469E), in coronary artery disease and myocardial infarction.

BACKGROUND: Inflammation plays a critical role in atherogenesis. The initial step in atherosclerosis is the adhesion of leukocytes to activated endothelial cells mediated by ICAM-1, an inflammatory protein. Several polymorphisms for Intracellular adhesion molecule -1(ICAM-) gene have been described. OBJECTIVES: To determine the possible role of G241R and K469E polymorphisms in development of coronary artery disease and MI. METHODS: G241R polymorphism was investigated in 303 patients with angiographically documented CAD, including 151 patients with acute or chronic myocardial infarction (MI), and a control group consisting of 141 healthy subjects with normal coronary angiogram. K469E polymorphism was investigated in 309 patients with CHD, including155 patients with MI, and compared with 150 healthy subjects without CHD as the control group. Finally, G241R and K469R polymorphisms were assessed concurrently in 300 patients with CHD including 152 patients with MI and 140 healthy normal subjects without coronary heart disease (CHD). RESULTS: Although the frequency of GR and RR genotypes were higher in the control group compared to the CHD patients, the difference was not statistically significant (7.09% vs. 5.6% and 1.4% vs. 0%, P=0.27and P=0.24, respectively). Despite the higher frequency of KK genotype in the CHD group, the difference was not significant (29.1% vs. 24.6%, P=0.62). KKGG genotype was more frequent in the CHD group, however the difference was not significant (31.1% vs. 27.3%, P=0.66). CONCLUSION: No strong relation was found between G241R and K469E polymorphisms and occurrence of CHD and MI in the studied population from Fars province, Iran.
