Coronary heart disease is the leading cause of death worldwide; accounting for 17.9 million deaths per year.[6]World Health Organization. Fact sheet: cardiovascular diseases (CVDs). Jun 2021 [internet publication].

Ischemic heart disease (IHD) is the most common cause of cardiovascular death; data from the European Society of Cardiology in 2019 showed that IHD accounted for 38% of cardiovascular disease (CVD) deaths in females and 44% in males.[3]Byrne RA, Rossello X, Coughlan JJ, et al. 2023 ESC Guidelines for the management of acute coronary syndromes. Eur Heart J. 2023 Oct 12;44(38):3720-826.

The incidence and mortality of ischemic heart disease has decreased in high-income countries over the past 30 years, which may be due to better control of risk factors such as hypertension, diabetes, high cholesterol, and smoking.[8]GBD 2019 Risk Factors Collaborators. Global burden of 87 risk factors in 204 countries and territories, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019. Lancet. 2020 Oct 17;396(10258):1223-49.

However, mortality is increasing in developing and transitional countries, with more than 75% of CVD deaths occurring in developing countries.[6]World Health Organization. Fact sheet: cardiovascular diseases (CVDs). Jun 2021 [internet publication].

These trends reflect changes in population longevity, urbanization, and lifestyle changes.[6]World Health Organization. Fact sheet: cardiovascular diseases (CVDs). Jun 2021 [internet publication].

Despite the overall reduction in incidence, in the US it is estimated that >800,000 people will experience an acute myocardial infarction (MI) each year.[5]Rao SV, O'Donoghue ML, Ruel M, et al. 2025 ACC/AHA/ACEP/NAEMSP/SCAI guideline for the management of patients with acute coronary syndromes: a report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines.

MI affects both men and women, but tends to occur at a younger age in men. The average age of a person having a first MI is 65.6 years for men and 72 years for women.[9]Martin SS, Aday AW, Allen NB, et al. 2025 heart disease and stroke statistics: a report of US and gobal data from the American Heart Association.

The incidence in women increases after menopause. Women ages under 60 years with ST-elevation myocardial infarction have higher 30-day mortality rates even after adjustment for medications, primary percutaneous coronary intervention, and other coexisting comorbidities.[10]Cenko E, Yoon J, Kedev S, et al. Sex differences in outcomes after STEMI: effect modification by treatment strategy and age. JAMA Intern Med. 2018 May 1;178(5):632-9.

About 90% of patients with coronary heart disease report at least one major risk factor, including cigarette smoking, dyslipidemia, hypertension, diabetes, and abdominal obesity.[11]Yusuf S, Hawken S, Ounpuu S, et al; INTERHEART Study Investigators.
