Genes involved in hemostasis and coagulation are excellent candidate genes for CAD and its thrombotic complications, i.e., myocardial infarction (MI) and unstable angina.
The association of the ACE gene with MI or CAD observed in other studies could not be confirmed in the present series of Chinese and Indians in Singapore.
In a population with a clear-cut definition of the phenotype, the G20210A prothrombin mutation was not significantly associated, per se, with either angiographically documented CAD or myocardial infarction, whereas it significantly influenced prothrombin activity.
Recent genome-wide association studies have identified 4 SNPs on chromosome 9p21 associated with CAD (rs10757274 and rs2383206) and myocardial infarction (MI: rs2383207 and rs10757278) in White populations in Northern Europe and North America.
Moreover, strong evidence was found for an increased risk for MI among carriers of the TT genotype who were smokers, hypertensive and had a family history of CAD.
The carriers of this allele have high levels of MMP-9 activity, LDL-C, TC and homocysteine (P=0.01), thus, are more likely to develop myocardial infarction and CAD at young age (less than 55 years).
The current analysis included 192 unrelated hypertensive patients, 261 patients with angiographically documented CAD (153 with myocardial infarction and 108 without myocardial infarction), and 496 population controls.
Major cardiovascular event rates at 12 months for patients with obstructive CAD and normal stress CTP (N = 61) were low: 1 myocardial infarction, 1 urgent revascularization, and 1 non-cardiac death.
Among the 60 CAD genes, the strongest association was with NBEAL1 that was also identified in gene-based analysis of whole exome sequencing for early onset myocardial infarction.
Patients at risk of adverse events beyond 12 months after an ACS may be identified by simple clinical and angiographic characteristics such as age, diabetes, chronic kidney disease, prior MI and multivessel CAD.
Although regular physical activity improves obstructive sleep apnea (OSA) in the general population, this finding has not been assessed in postmyocardial infarction (MI) patients in a rehabilitation setting (coronary artery disease, CAD).
The incremental prognostic value of myocardial ischemia from SPECT myocardial perfusion imaging (MPI) over clinical characteristics, cardiac risk factors, and stress test data for the prediction of hard cardiac events (myocardial infarction and cardiac death) has been well demonstrated over the last two decades regardless of the absence or presence of epicardial CAD.
ML plaques, indicative of prior thrombosis, were frequently identified in patients with CAD, particularly more so in SAP and those with prior MI compared with ACS.
Compared with the myocardial infarction with obstructive coronary arteries (MI-CAD) patients, the prevalence of traditional risk factors of CAD was lower in MINOCA patients.
Patients with previous myocardial infarction (MI) presented with 20% shorter LTLs vs. patients without (p = 0.019) indicating LTLs to be of importance for CAD severity.
