What is ischemic heart disease?

Here, we are going to share information about what is ischemic heart disease? Ischemic heart disease, commonly referred to as coronary heart disease, is a condition in which the heart muscle’s blood supply is restricted due to a partial or whole blockage of the arteries supplying it. If we think of the coronary arteries as a network of tubes, then as they gradually clog, the liquid that is supposed to be flowing through them—blood in this case—does not arrive at the heart as intended.

Angina pectoris or a heart attack are brought on by inadequate blood flow to the heart due to a blocked coronary artery. Ischemic heart disease, often known as coronary heart disease, is one of the main causes of death worldwide for both men and women. It is usually preventable and asymptomatic. Both in industrialised and emerging nations, ischemic heart disease is a rather prevalent ailment that impacts a significant portion of the population.

It is estimated that 15.4 million Americans over the age of 20 have ischemic heart disease, accounting for 6.4 percent of the country’s total population (7.9 percent of men and 5.1 percent of women).According to estimates, cardiovascular disease accounts for 4 million deaths annually in Europe, or 47% of all fatalities.

Even in the elderly, the prevalence of ischemic heart disease rises with age and is higher in men than in women. Research indicates that the prevalence of coronary heart disease is twice as high in men and three times higher in women between the ages of 65 and 94 as it is in those between the ages of 35 and 64.

Angina pectoris is the characteristic symptom of ischemic heart disease in women, whereas myocardial infarction, or heart attack, is the most common manifestation in men.In either case, the leading cause of mortality for adults in both developing and wealthy nations continues to be ischemic heart disease.

What is the main cause of ischemic heart disease?

A person’s myocardial ischemia is frequently caused by multiple factors.

Heart artery disease: The accumulation of plaque and cholesterol within the coronary arteries, which provide blood to the heart muscle, is what causes this. Your heart muscle becomes oxygen-starved as a result of the buildup, narrowing your artery to such an extent that your heart is unable to get the oxygen-rich blood it needs. Angina and ischemia result from this. Seventy percent of deadly heart attacks are caused by atherosclerotic plaque.

Blood clot: A blood clot may form when plaque that has built up in your narrow coronary artery breaks away. A blockage may result from a blood clot settling in an already-narrow coronary artery (thrombosis).

Angina pectoris spasm: This occurs when your heart’s blood flow is momentarily reduced or stopped by a spasm in the coronary arteries.

Cocaine used: overconsumption can lead to ischemic heart disease.

Dissection of the coronary artery: This uncommon ailment may prevent blood from reaching your heart.

The most common cause of ischemia is when the heart isn’t getting enough oxygen and nutrients. It occurs when your heart cannot pump enough blood to meet your body’s growing needs.

More blood is required by your body when you’re

  • Active/exercising
  • Eating
  • Stressed
  • Excited
  • Cold

Ischemic heart disease Symptoms

There are some myocardial ischemia patients who show no symptoms at all (silent ischemia). When they do, chest pressure or pain is the most prevalent, usually on the left side of the body (angina pectoris). Additional symptoms and indicators that may be more prevalent in women, the elderly, and those with diabetes

  • Jaw or neck ache
  • Arm or shoulder pain
  • An accelerated heart rate
  • Breathing difficulties with vigorous activity
  • Vomiting and nausea
  • Sweating /fatigue

Heart Failure Stages: Ischemic heart disease

Because heart failure can worsen, scientists have classified the condition into four phases: A, B, C, and D. When heart failure reaches stages C and D, medical practitioners also categorise it. The overall cardiac function and symptom severity of a patient are measured by this classification.

Stage A: Heart failure is possible.

Individuals who do not yet exhibit symptoms of structural or functional heart disease but are at risk for heart failure. Risk factors for individuals in this stage include exposure to cardiotoxic substances, genetic variations for cardiomyopathy, obesity, diabetes, coronary vascular disease, hypertension, and a family history of cardiomyopathy.

Pre-heart failure, stage B

Individuals with structural heart disease, elevated heart filling pressures, or other risk factors who do not already exhibit heart failure symptoms

Stage C: Heart failure with symptoms

those who exhibit heart failure symptoms either now or in the past

Stage D: Severe cardiac failure

Individuals whose symptoms of heart failure cause them to go to the hospital frequently or interfere with their everyday activities


Factors at risk include ischemic heart failure

The following variables may make you more susceptible to myocardial ischemia:

Tobacco: The inside walls of arteries can be harmed by smoking and prolonged exposure to secondhand smoke. Damage to the coronary arteries can lead to the accumulation of deposits of cholesterol and other materials, which can decrease blood flow. Smoking raises the risk of blood clots and causes the coronary arteries to spasm.

Diabetes: An increased risk of myocardial ischemia, heart attacks, and other heart issues is associated with both type 1 and type 2 diabetes.

Elevated blood pressure: High blood pressure can damage the coronary arteries by hastening the process of atherosclerosis over time.

Elevated cholesterol in the blood: One of the main deposits that can cause your coronary arteries to narrow is cholesterol. A diet heavy in saturated fats and cholesterol, or an inherited disorder, may be the cause of a high amount of “bad” (low-density lipoprotein, or LDL) cholesterol in your blood.

Elevated triglyceride level in the blood: Another form of blood fat called triglycerides may potentially be involved in atherosclerosis.

Obesity: Diabetes, high blood pressure, and elevated blood cholesterol are linked to obesity.

circumference of the waist: A waist measurement above 35 inches (89 centimetres) for females and 40 inches (102 cm) for males is associated with an increased risk of hypertension, diabetes, and cardiovascular disease.

Absence of exercise: Insufficient exercise raises the risk of obesity and is associated with elevated levels of triglycerides and cholesterol. Regular aerobic exercisers have healthier hearts, which is linked to a decreased risk of myocardial ischemia and myocardial infarction. Blood pressure is also lowered by exercise.


Complications associated with ischemic heart disease

Serious consequences from myocardial ischemia can include

Heart attack: A heart attack that results in the partial destruction of the heart muscle can occur if a coronary artery becomes totally clogged due to a shortage of blood and oxygen. There may be fatalities or significant damage.

Abnormal cardiac beat (arrhythmia): Your heart may become weaker from an irregular cardiac rhythm, which could even be fatal.

Heart breakdown: Heart failure may develop over time as a result of recurrent ischemia episodes.

How is myocardial ischemia treated?

Handling and Medical Interventions

Treatments for myocardial ischemia may involve drugs or operations that increase blood flow to the heart muscle. The reason for the issue will determine how you are treated for myocardial ischemia. You will discuss the best course of therapy with your healthcare professional.

Which drugs or therapies are applied?

Treatments or medications for myocardial ischemia could consist of

  • Nitroglycerin can relieve angina symptoms quickly.
  • Beta-blockers.
  • Blockers of calcium channels.
  • Thrombolytic agents (clot-busting drugs).
  • Implantation of stents and angioplasty.
  • Grafting a coronary artery bypass.


The same way of life that can be used to treat myocardial ischemia can also be used to stop it from ever occurring. Maintaining an active lifestyle will help keep your arteries flexible, robust, and smooth so that blood can flow through them as much as possible.


In conclusion, understanding ischemic heart disease is crucial for individuals seeking to prioritize heart health. This silent yet pervasive condition demands our attention, emphasizing the significance of adopting a heart-healthy lifestyle. From lifestyle modifications to medical interventions, the journey to mitigate the impact of ischemic heart disease requires collective awareness and proactive measures. By staying informed, making informed choices, and fostering a culture of heart-conscious living, we pave the way towards a healthier future where the burden of ischemic heart disease is diminished and lives are enriched through cardiovascular well-being.
