Treatment Options for Cardiac Ischemia

Goals of Cardiac Ischemia Treatment

Cardiac ischemia [ih-SKEE-mee-uh] also called myocardial ischemia, occurs when the heart muscle doesn’t receive enough oxygen and blood to work properly and pump blood to the body. This may cause symptoms such as chest pressure or pain, shortness of breath, sweating, and fatigue. It may also lead to complications including heart attack, heart arrhythmia, and heart failure.

The goals of treatment for cardiac ischemia are to:

Alleviate symptoms
Improve blood flow
Reduce the risk of complications
Slow disease progression

Treatment can help manage symptoms and improve quality of life, but it may not completely reverse the underlying condition.

Cardiac Ischemia Treatment Options

Cardiac ischemia treatment focuses on improving blood flow to the heart, relieving symptoms such as angina, and lowering the risk of heart attack, heart failure, abnormal heart rhythms, and death. Treatment may include heart-healthy lifestyle changes, medicines, cardiac rehabilitation, and, for some people, a procedure or surgery to restore blood flow. The recommended approach depends on whether symptoms are stable or urgent, the severity and location of artery narrowing, other medical conditions, and patient preferences:

Lifestyle Changes for Cardiac Ischemia:
Dietary changes: A heart-healthy eating pattern that emphasizes fruits, vegetables, whole grains, lean proteins, and healthy fats, while limiting saturated fats, trans fats, sodium, added sugars, and excess alcohol, can help manage blood pressure, cholesterol, weight, and diabetes risk.
Physical activity: Regular physical activity can improve cardiovascular fitness and help manage risk factors such as high blood pressure, high cholesterol, obesity, and diabetes. People with cardiac ischemia should ask a healthcare professional what level of activity is safe, especially if symptoms are new, worsening, or occur with exertion.
Smoking and vaping cessation: Quitting smoking and avoiding nicotine products are important because tobacco and nicotine can damage blood vessels and increase the risk of heart attack and other cardiovascular problems.
Risk-factor management: Managing blood pressure, cholesterol, blood sugar, weight, sleep, and stress can help slow progression of coronary artery disease and reduce the risk of future cardiovascular events.
Medications for Cardiac Ischemia:
Antiplatelet medicines: Aspirin or another antiplatelet medicine may be recommended for some people to help prevent blood clots that can block coronary arteries. These medicines can increase bleeding risk, so they should be used only as directed by a healthcare professional.
Statins and other cholesterol-lowering medicines: Statins lower LDL cholesterol and help reduce the risk of future heart attack and stroke. Additional cholesterol-lowering medicines may be considered if LDL cholesterol remains above the recommended goal.
Beta-blockers: These medicines slow the heart rate, lower blood pressure, and reduce the heart’s oxygen demand. They may help relieve angina and are commonly used after a heart attack or in certain people with heart failure or abnormal heart rhythms.
Nitrates: Nitroglycerin and other nitrates relax and widen blood vessels, which can improve blood flow and relieve angina. Short-acting nitroglycerin may be used for sudden chest pain as prescribed.
Calcium channel blockers: These medicines relax blood vessels and may reduce the heart’s workload. They can be useful for angina, high blood pressure, or coronary artery spasm.
ACE inhibitors or ARBs: These blood pressure medicines may be recommended for people with high blood pressure, diabetes, chronic kidney disease, heart failure, or prior heart attack to help reduce cardiovascular risk.
Ranolazine: This medicine may be used to help reduce angina symptoms, particularly when symptoms continue despite other medicines or when other options are not tolerated.
Procedures and Surgery for Cardiac Ischemia:
Coronary angioplasty and stent placement: Also called percutaneous coronary intervention, this procedure uses a catheter with a small balloon to open a narrowed or blocked coronary artery. A stent is often placed to help keep the artery open. It may be used during a heart attack, for worsening or persistent angina, or when medicines and lifestyle changes do not adequately control symptoms.
Coronary artery bypass grafting: This surgery creates a new route for blood to flow around blocked or narrowed coronary arteries. It may be recommended for certain people with more extensive coronary artery disease, left main coronary artery disease, diabetes with multivessel disease, or symptoms that are not controlled with other treatments.
Cardiac rehabilitation: A supervised program that combines exercise, education, risk-factor management, and counseling may be recommended after a heart attack, stent procedure, bypass surgery, or for some people with ongoing heart disease to improve recovery and quality of life.

A healthcare professional can recommend a treatment plan based on symptom severity, test results, overall health, and personal preferences. People should seek emergency medical help for chest pain or pressure that is severe, new, worsening, occurs at rest, or does not improve with rest or prescribed nitroglycerin, or if chest symptoms occur with shortness of breath, sweating, nausea, fainting, or pain spreading to the arm, jaw, neck, back, or shoulder.
