Coronary Atherosclerosis: Causes, Symptoms & Treatment
Coronary atherosclerosis, also known as narrowing of the heart arteries, occurs when fatty deposits build up in the blood vessels supplying the heart. These deposits can restrict blood flow, leading to potential complications. Factors like diet, lifestyle choices, and genetics can contribute to this condition. It's essential to understand the impact of these factors on heart health to make informed decisions.
By making healthy choices and managing risk factors, you can potentially reduce your chances of developing coronary atherosclerosis. Prioritizing heart-healthy habits is key to promoting overall well-being and preventing heart-related issues.
Symptoms of Coronary Atherosclerosis
Some people may experience dizziness, nausea, or sweating. In severe cases, it can lead to a heart attack. Seeking medical attention promptly is crucial if you experience any of these symptoms. Making lifestyle changes and following a treatment plan can help manage the condition and prevent complications.
- Chest pain or discomfort, often described as tightness, pressure, or squeezing in the chest area, especially during physical activity or emotional stress.
- Shortness of breath, particularly with exertion or when lying down, due to reduced blood flow to the heart muscle.
- Fatigue or weakness, even with mild physical activity, as the heart struggles to pump enough oxygen-rich blood throughout the body.
- Dizziness or lightheadedness, which may occur when the heart is not able to pump enough blood to the brain.
- Nausea or indigestion, especially in women, as coronary atherosclerosis can cause referred pain to the abdomen or lead to gastrointestinal disturbances.

Contributing factors include high cholesterol, high blood pressure, smoking, diabetes, obesity, and a sedentary lifestyle. Genetics and age also play a role in the development of this condition. Early detection and lifestyle modifications are key in managing coronary atherosclerosis.
- High cholesterol levels in the blood can lead to the buildup of plaque in the arteries, causing coronary atherosclerosis.
- Smoking tobacco products damages the inner lining of blood vessels, increasing the risk of atherosclerosis in the coronary arteries.
- Hypertension, or high blood pressure, puts strain on the heart and blood vessels, contributing to the development of coronary atherosclerosis.
- Diabetes mellitus, especially when poorly controlled, can accelerate the progression of atherosclerosis in the coronary arteries.
- Sedentary lifestyle and lack of physical activity are risk factors for coronary atherosclerosis as they can lead to obesity and other metabolic disturbances.
Types of Coronary Atherosclerosis
- Stable Coronary Artery Disease: This type of coronary atherosclerosis is characterized by the gradual buildup of plaque in the arteries supplying the heart, leading to predictable chest pain or discomfort during physical activity or stress.
- Unstable Angina: A type of coronary atherosclerosis that presents as sudden chest pain or discomfort at rest or with minimal exertion, indicating a vulnerable plaque that could potentially rupture and lead to a heart attack.
- Acute Myocardial Infarction (Heart Attack): This severe form of coronary atherosclerosis occurs when a coronary artery becomes completely blocked by a blood clot, leading to a sudden interruption of blood flow to the heart muscle, causing damage.
Risk Factors
Risk factors for coronary atherosclerosis include high blood pressure, high cholesterol levels, smoking, diabetes, obesity, lack of physical activity, unhealthy diet, and family history of heart disease.
These factors contribute to the buildup of plaque in the arteries, leading to restricted blood flow to the heart. Managing these risk factors is crucial in preventing coronary artery disease and related complications.
- Smoking tobacco increases the risk of coronary atherosclerosis by promoting the buildup of plaque in the arteries.
- Uncontrolled hypertension can accelerate the development of coronary atherosclerosis by causing damage to the arterial walls.
- High levels of LDL cholesterol, known as the "bad" cholesterol, can lead to the deposition of plaque in the coronary arteries, increasing the risk of atherosclerosis.
- Sedentary lifestyle and lack of regular physical activity are risk factors for coronary atherosclerosis as they can contribute to obesity and poor cardiovascular health.
- Diabetes mellitus, especially when poorly controlled, can significantly increase the risk of developing coronary atherosclerosis due to its effects on blood sugar levels and blood vessel health.

Diagnosis of Coronary Atherosclerosis
Your healthcare provider may also recommend a stress test to evaluate your heart's function during physical activity. These tests help determine the extent of blockages in your coronary arteries and guide treatment decisions.
- Coronary angiography is a common diagnostic method for coronary atherosclerosis that involves injecting contrast dye into the coronary arteries to visualize blockages.
- Cardiac CT angiography is a non-invasive imaging test that uses computed tomography to create detailed images of the heart and coronary arteries to detect plaque buildup.
- Stress tests, such as exercise stress tests or pharmacological stress tests, can help assess blood flow to the heart muscle and identify areas with reduced blood flow due to coronary artery disease.
- Intravascular ultrasound (IVUS) is a procedure that uses a tiny ultrasound device inserted into the coronary arteries to provide detailed images of the vessel walls and any plaque buildup.
Treatment for Coronary Atherosclerosis
Treatment options for coronary atherosclerosis include lifestyle modifications, such as a heart-healthy diet and regular exercise, to manage risk factors like high cholesterol and blood pressure.
Medications like statins, aspirin, and blood thinners may be prescribed to reduce plaque buildup and prevent blood clots. In more severe cases, procedures such as angioplasty or bypass surgery may be recommended to improve blood flow to the heart.
- Lifestyle modifications, such as adopting a heart-healthy diet low in saturated fats and cholesterol, engaging in regular physical activity, and quitting smoking, are essential in managing coronary atherosclerosis.
- Medications like statins, antiplatelet drugs, ACE inhibitors, and beta-blockers may be prescribed by a healthcare provider to help lower cholesterol levels, prevent blood clots, reduce blood pressure, and manage symptoms of coronary atherosclerosis.
- Invasive procedures like angioplasty and stent placement or coronary artery bypass grafting (CABG) may be recommended for individuals with severe coronary atherosclerosis to improve blood flow to the heart muscle.
