Ischemic Heart Disease Statistics: Ischemic Heart Disease, also known as Coronary Heart Disease (CHD) or Coronary Artery Disease (CAD), is a common and severe medical condition that affects the heart. It is characterized by reduced blood flow to the heart muscle, leading to inadequate oxygen supply, and subsequently, damage to the heart tissue. The primary cause of IHD is the gradual build-up of fatty deposits, known as plaques, within the coronary arteries that supply blood to the heart.
IHD is a leading cause of death globally and is responsible for a significant proportion of cardiovascular-related mortality. It can lead to various complications, including angina (chest pain), heart failure, arrhythmias (irregular heartbeats), and even sudden cardiac death.
- IHD is the leading cause of death globally, accounting for approximately 16% of all deaths.
- In the United States, IHD is responsible for more than 1 in 7 deaths, making it the leading cause of mortality.
- Approximately 17.9 million people died from cardiovascular diseases, including IHD, in 2022, representing 32% of all global deaths.
- IHD is more common in men than women, with men having a higher risk of developing the condition.
- High blood pressure, smoking, and high cholesterol are significant risk factors for IHD.
- As of 2021, it was estimated that around 240 million people worldwide were living with IHD.
- IHD is responsible for a substantial economic burden, including healthcare costs and lost productivity, amounting to billions of dollars globally.

- Acute Myocardial Infarction (Heart Attack)
- Acute myocardial infarction, commonly known as a heart attack, is a life-threatening condition resulting from reduced or blocked blood flow to the heart muscle.
- Each year, there are approximately 805,000 heart attacks in the United States, with about 605,000 being first heart attacks and 200,000 recurrent attacks.
(Source: American College of Cardiology, American Heart Association)

Ischemic Heart Disease Statistics – Ischemic heart disease remains a significant global health burden, accounting for a substantial number of deaths and disabilities each year. The prevalence of this condition is still on the rise due to various risk factors, such as sedentary lifestyles, unhealthy diets, and increasing aging populations. Despite advancements in medical treatments and interventions, preventive measures and public health initiatives play a crucial role in reducing the incidence and impact of ischemic heart disease. Continued research and awareness are essential to address this critical issue and improve cardiovascular health worldwide.
Ischemic Heart Disease, also known as Coronary Artery Disease (CAD), is a condition where the blood flow to the heart muscle is reduced or blocked due to the narrowing or obstruction of the coronary arteries. It is the most common type of heart disease and a leading cause of heart attacks.
Several factors can increase the risk of developing IHD, including:
• High blood pressure (hypertension)
• High cholesterol levels
• Family history of heart disease
• Lack of physical activity
• Unhealthy diet (high in saturated and trans fats)
The common symptoms of IHD include:
• Chest pain or discomfort (angina), typically experienced as pressure, squeezing, or tightness in the chest
• Pain or discomfort in the arms, neck, jaw, shoulder, or back
• Shortness of breath
Treatment aims to improve blood flow to the heart, alleviate symptoms, and prevent complications. Options may include lifestyle changes, medications (e.g., aspirin, statins, beta-blockers, and nitroglycerin), angioplasty with stent placement, or bypass surgery.
