Overview

Coronary Artery Disease (CAD) is a common heart condition in which the blood vessels supplying oxygen-rich blood to the heart muscle become narrowed or blocked. It usually develops when fatty deposits, cholesterol, and other substances build up inside the coronary arteries, a process known as atherosclerosis. As the arteries become narrower, the heart may receive less oxygen, particularly during physical activity or emotional stress.

Coronary artery disease can develop gradually and may not cause noticeable symptoms in its early stages. When symptoms occur, they may include chest discomfort, breathlessness, fatigue, sweating, or pain that spreads to the arm, shoulder, neck, jaw, or back. In some people, the first sign may be a heart attack.

Early diagnosis and timely Coronary Artery Disease Treatment can help control symptoms, reduce the risk of heart attack, and protect long-term heart function. At Sarvodaya Hospital, our cardiology team provides comprehensive evaluation and personalised treatment using advanced cardiac imaging, interventional cardiology procedures, medical management, and surgical care when required.

Symptoms of Coronary Artery Disease

• Chest pain or discomfort
• Pressure, tightness, heaviness, or squeezing in the chest
• Breathlessness, particularly during exertion
• Unusual tiredness or fatigue
• Pain or discomfort spreading to the arm, shoulder, neck, jaw, or back
• Dizziness or light-headedness
• Sweating
• Nausea
• Reduced exercise tolerance
• Fast or irregular heartbeat

Causes of Coronary Artery Disease

• High LDL cholesterol
• High blood pressure
• Diabetes
• Smoking
• Obesity
• Physical inactivity
• Unhealthy diet
• Increasing age
• Family history of heart disease
• Chronic stress
• Certain inflammatory or metabolic conditions

Risk Factors for Coronary Artery Disease

Several factors can increase the risk of developing CAD.

• High Blood Pressure : Persistent high blood pressure can damage the inner lining of the arteries and accelerate plaque formation.
• High Cholesterol : High levels of LDL cholesterol can contribute to fatty deposits inside the coronary arteries.
• Diabetes : High blood sugar can damage blood vessels and significantly increase cardiovascular risk.
• Smoking : Tobacco smoke damages blood vessels, promotes plaque formation, and increases the risk of blood clots.
• Obesity : Excess body weight is associated with high blood pressure, diabetes, abnormal cholesterol, and other factors that increase cardiovascular risk.

Diagnosis of Coronary Artery Disease

Accurate diagnosis helps determine whether coronary arteries are narrowed or blocked and assesses the risk of future cardiac events.

• Medical History and Clinical Examination:The cardiologist reviews symptoms, family history, lifestyle, medications, and existing conditions such as diabetes or hypertension.
• Electrocardiogram (ECG) : An ECG records the heart's electrical activity and may identify changes associated with reduced blood flow or previous heart damage.
• Echocardiography : An echocardiogram uses ultrasound to assess heart structure, pumping function, and movement of the heart muscle.
• Blood Tests : Blood investigations may include cholesterol, blood glucose, kidney function, and cardiac biomarkers when a heart attack is suspected.
• Stress Testing : Exercise or pharmacological stress testing can help assess how the heart responds to increased workload and whether symptoms may be related to reduced blood flow.

Treatment Options for Coronary Artery Disease

The most suitable Coronary Artery Disease Treatment Options depend on the severity and location of coronary artery blockage, symptoms, overall heart function, and other health conditions. Treatment may involve lifestyle changes, medicines, angioplasty, stent placement, or coronary artery bypass surgery.

• Lifestyle Modification : Healthy lifestyle changes are an important part of CAD management. These include a heart-healthy diet, regular physical activity as advised by the cardiologist, smoking cessation, weight management, stress management, and control of blood pressure, blood sugar, and cholesterol.
• Medication Therapy : Depending on individual needs, medicines may be prescribed to control cholesterol and blood pressure, reduce the risk of blood clots, improve blood flow, or relieve symptoms such as angina.
• Angioplasty and Stent Placement : Percutaneous Coronary Intervention (PCI), commonly called angioplasty, uses a catheter to open a narrowed coronary artery. A stent may be placed to help keep the artery open.

Benefits of Early Coronary Artery Disease Treatment

Timely Coronary Artery Disease Treatment can help reduce symptoms and lower the risk of serious cardiac complications.

• Reduces Risk of Heart Attack:  Early management can help control coronary artery blockage and reduce the risk of acute cardiac events.
• Controls Symptoms : Appropriate medicines and procedures can relieve angina, breathlessness, and reduced exercise tolerance.
• Protects Heart Function : Timely treatment helps maintain adequate blood supply to the heart muscle and may prevent further damage.
• Slows Disease Progression : Managing cholesterol, blood pressure, diabetes, smoking, and other risk factors can slow the progression of atherosclerosis.

Complications if Left Untreated

• Angina
• Heart attack
• Heart failure
• Abnormal heart rhythms
• Reduced heart pumping function
• Cardiogenic shock in severe cases
• Sudden cardiac arrest
• Reduced exercise capacity
• Death

When Should You See a Doctor?

• Recurrent chest discomfort
• Chest pressure or tightness during activity
• Breathlessness while walking or exercising
• Unexplained fatigue
• Reduced exercise tolerance
• Pain spreading to the arm, shoulder, jaw, neck, or back
• Dizziness or light-headedness
• Repeated sweating or nausea with exertion
• A strong family history of heart disease
• Diabetes, high blood pressure, or high cholesterol with new cardiac symptoms

Prevention & Lifestyle Modifications

Healthy lifestyle habits play an important role in preventing and managing coronary artery disease.

• Follow a Heart-Healthy Diet : Include vegetables, fruits, whole grains, pulses, nuts, and other nutrient-rich foods while limiting excess saturated fat, trans fats, salt, and highly processed foods.
• Stay Physically Active : Regular physical activity helps maintain cardiovascular fitness. Patients with diagnosed CAD should follow an exercise programme recommended by their cardiologist.
• Control Blood Pressure : Regular blood pressure monitoring and prescribed treatment help reduce strain on the heart and blood vessels.
• Manage Cholesterol : Regular cholesterol testing and prescribed medicines, when required, can help control LDL cholesterol and reduce cardiovascular risk.
• Manage Diabetes : Maintaining appropriate blood glucose levels helps protect blood vessels and reduce cardiovascular complications.

Pre- and Post-Treatment Care

Pre-Treatment

• Pre-procedure evaluation before angioplasty or surgery

Post-Treatment

• Taking prescribed medicines regularly
• Monitoring blood pressure and blood sugar
• Following cholesterol management advice
• Adopting a heart-healthy diet
• Gradually increasing physical activity
