JAHA: Five-year risk of acute myocardial infarction after acute ischemic stroke

The long-term occurrence of acute myocardial infarction (AMI) in patients with acute ischemic stroke (AIS) has not been defined in large-scale queue studies of different races.
, researchers identified AIS patients enrolled in the multi-center National Stroke Registry to form a forward-looking queue of AIS patients to follow up on the AMI's incidence by linking to the National Health Insurance Service Claims Database, according to a recent study published in JAHA, an authoritative journal in the field of cardiovascular disease.
estimates of cumulative morbidity and annual risk over a five-year basis based on predefined demographic subgroups, stroke-type, coronary heart disease (CHD) disease histories, and known CHD risk factors.
the study analyzed 11,720 AIS patients with a 5-year cumulative AMI rate of 2.0%.
the first year after the incident, the annual risk was highest (1.1 per cent) and the annual risk was lower in the second to fifth years (0.16 to 0.27 per cent).
in the subgroup, people with a history of coronary heart disease had the highest annual risk in the first year (4.1%), while those without a history of coronary heart disease had the highest risk in the first year (0.8%).
the occurrence of small vascular astrations (2.2%) or cardiac embolism (2.4%) subtypes was relatively low (0.8%).
in the multivariable analysis, coronary heart disease history (risk ratio of 2.84; 95% CI of 2.01-3.93) was the strongest independent predictor of AMI after AIS.
, the AMI rate of AIS patients is relatively low and the highest in the first year after stroke.
CHD is the most important risk factor for AMI after stroke, with a risk increase of about five times.
