Acute Myocardial Infarction: The First Manifestation of Ischemic Heart Disease and Relation to Risk Factors

Abstract

Objective -To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. Methods - (RR=0.19; P=0.04) and left ventricular hypertrophy (RR=0.27; 95% CI=0, P=0.03). The remaining risk factors were not statistically significant. Conclusion -Prevalence of acute myocardial infarction as the first manifestation of ischemic

Evaluation of risk factors in acute myocardial infarction patients admitted to the coronary care unit, Tripoli Medical Centre, Libya

“…CHD continues to be one of the major causes of morbidity and mortality among women as well as men in many countries [1,5]. CHD is much less frequent in premenopausal women than in age-matched men [12].…”

“…Hypertensive individuals more frequently have symptoms preceding acute MI, probably due to ventricular hypertrophy associated with high blood pressure [5]. Women with acute ischaemic syndromes have higher rates of associated diabetes and hypertension because the protective effects of the premenopausal state can probably be overcome by these 2 potent causes of atherosclerosis [13].…”

“…More recently, it has been concluded in one study in Benghazi that circulatory diseases were still the main cause of death in diabetics, with acute myocardial infarction (MI) at the top of the list [3]. The prevalence of acute MI as the first manifestation of ischaemic heart diseases is high in approximately 50% to 70% of patients and is a common cause for hospital admission [5]. Several factors related to the severity of the disease have been identified, such as smoking [6], diabetes mellitus [7], systemic arterial hypertension [8], dyslipidaemia [1], the number of arteries impaired and degree of functional impairment of the left ventricle [9].…”

Sex differences in myocardial infarct size are abolished by sarcolemmal KATPchannel blockade in rat

“…ISCHEMIC HEART DISEASE is the leading cause of death in both males and females in the industrialized world, with myocardial infarction being the most common manifestation of ischemic heart disease (18). Among humans, premenopausal women have a lower risk of cardiovascular disease than age-matched men, and there is growing evidence that there is a sex-specific difference in the susceptibility of the myocardium to infarction after ischemia in dogs (15), rats (1,4), mice (10,11), as well as in humans (19).…”

A Descriptive Study on Risk Factors among Acute Myocardial Infarction Patients Admitted to the Coronary Care Unit of Prince Mitab Hospital Sakaka Aljouf

“…Hypertension is known to cause ventricular hypertrophy that probably lead to earlier symptoms of MI and also forces patients to seek care, hence being recorded more frequently in patients admitted with MI. [25] A recent study suggested that smoking is an important contributor to MI under the age of 36 Years. [24] Smoking increases the initial and subsequent risk MI and death.…”
