What takes place in your heart when there is reduced blood supply to the heart? Ischemic heart disease may develop slowly and without symptoms as the arteries become clogged with plaque. Knowing what takes place helps you to understand the causes, testing, and treatment for heart problems.

One method doctors use to evaluate your heart for coronary artery disease is a heart scan. It can detect calcified plaque or narrowing of coronary arteries or give further information about the heart and its blood vessels.

Ischemic Heart Disease Definition

Ischemic heart disease refers to a condition that occurs when there is an inadequate supply of blood that contains oxygen to the heart muscles. The cause of ischemic heart disease is mainly coronary artery disease. It happens due to the presence of plaque deposits in the arteries supplying blood to the heart.

The plaque might consist of fat, calcium, cholesterol, and many other things. The plaque buildup can narrow the artery and thus reduce the amount of blood flowing through it. The heart might perform well during rest but have difficulty receiving adequate oxygen while working under conditions of physical activity or stress.

This inadequate blood supply results in ischemia, which in certain cases leads to chest pain.

What Causes Ischemic Heart Disease?

Ischemic heart disease tends to develop gradually over years and not all of a sudden. Various factors may cause the rapid development of plaques and make a person more prone to heart disease.

High blood pressure might damage arterial walls, whereas high levels of LDL cholesterol may contribute to the formation of plaques. Diabetes, smoking, being overweight, lack of physical activity, and family history of heart disease also increase the risk.

Another factor that increases the likelihood of developing the disease is age. However, coronary artery disease does not concern only older people. A person's risk is determined by their set of risk factors.

That is why even without any visible signs, a person who has various risk factors should consult a physician regarding their heart risks.

Effects of Ischemic Heart Disease on the Heart

It depends on how constricted the coronary arteries are and on whether any damage has occurred to the heart muscle.

Less oxygen leads to angina

When the heart requires more oxygen than can be supplied by the narrowed arteries, one experiences angina. It is the feeling of pressure or tightness in the chest and can happen during exercise.

Other signs are shortness of breath, sweating, nausea, or pain in areas such as the arm, shoulder, back, neck, or jaw. Any new or unusual signs must be taken seriously and not dismissed as digestion- or fatigue-related.

The blocked arteries could lead to a heart attack.

There may be a situation where the plaque ruptures and forms a blood clot. In cases where the blood flow through the coronary artery is greatly blocked, some parts of the heart muscle will lack oxygen supply. When this goes on for an extended period of time, there might be some damage to the heart muscle.

Ischemia and prior heart attacks could have an impact on the pumping capacity of the heart.

Heart scan for heart disease – How does it work?

The expression “heart scan” can refer to many types of imaging studies, which give various results.

In coronary artery calcium scoring, a patient’s coronary arteries are studied by CT scanning for the presence of any calcium deposits. A calcium score can provide some idea about the person’s future risk of heart problems and can aid the decision on preventive treatment for suitable candidates.

A CT coronary angiogram takes this a step further—it produces an image of the coronary arteries. In combination with the contrast dye, it allows for detecting plaque and narrowing in coronary arteries that are causing the symptoms.

Not all people are eligible for a calcium score test. According to the American Heart Association, some people who have had coronary artery disease and symptoms may need other tests.

What Is the Ischemic Heart Disease Prognosis?

The ischemic heart disease prognosis can vary from one person to another. The seriousness of the disease in the arteries, heart functionality, history of heart attacks, and management of risk factors can play a role.

There is therefore no reliable single number for ischemic heart disease life expectancy. Two people with the same diagnosis can have very different outcomes depending on the extent of disease and how effectively it is managed.

Can People Survive for a Long Time If They Have Ischemic Heart Disease?

Yes, the presence of this disorder does not necessarily imply that people will live a short life. Lifespan for patients with ischemic heart disease may be highly variable, and the correct treatment and risk factor management can make a significant difference.

People living with ischemic heart disease may require long-term treatment with medication, regular check-ups by a physician, exercise tailored to their individual condition, proper nutrition, and control of blood pressure, cholesterol levels, and diabetes. The current recommendations for chronic coronary heart disease stress the importance of proper nutrition and physical activity.

The most useful question is not only “How long am I going to live?” but “What should I do now to decrease my cardiovascular risk?”

Finding a Cardiovascular Imaging Service Provider

A diagnostic center like ViaScan of Las Colinas in Irving, Texas, may be one of the providers patients encounter when considering cardiovascular imaging services, including coronary calcium-focused scanning and other cardiac imaging options. These imaging services can provide additional information about coronary plaque and cardiovascular risk.

A patient considering this type of assessment may appreciate having imaging results that can be reviewed alongside their medical history and other risk factors. As with any diagnostic test, however, the scan itself should not replace professional medical interpretation.

Conclusion

Ischemic heart disease results from inadequate supply of oxygen-filled blood to the heart due to plaque deposits that narrow the coronary arteries. This can result in angina, heart muscle damage, and heart attack.

A heart scan may be quite helpful for knowing about coronary calcium or narrowing of the arteries; however, which test to conduct would depend on the patient's condition. If you are worried about your heart health, consult a qualified healthcare provider regarding your risks and need for cardiac imaging or other heart tests.
