Heart disease encompasses a range of conditions that can affect the heart and its ability to function optimally. Understanding the different types of heart disease can help you gain insight into how they impact your heart’s health and the potential treatment options available.

Coronary artery disease (CAD)

Coronary artery disease occurs when the arteries that supply blood to the heart become narrow or blocked due to the buildup of plaque. This limits blood flow to the heart, resulting in symptoms such as chest pain or discomfort (angina) and increasing the risk of a heart attack. Lifestyle modifications, medications, and procedures like stenting may be utilized to manage CAD.

Heart attack

A heart attack, also known as myocardial infarction, occurs when there is a blockage in the coronary arteries, cutting off the blood supply to the heart muscle. This can result in permanent damage to the heart muscle if not treated promptly. Symptoms of a heart attack may include chest pain, shortness of breath, and pain radiating to the arm, shoulder, jaw, neck, or back. Immediate medical attention is necessary in the event of a heart attack to minimize long-term damage.

Heart failure

Heart failure refers to a condition in which the heart is unable to pump blood effectively, leading to a reduced supply of oxygen and nutrients to the body’s tissues. This can result in symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles. Treatment for heart failure may involve medications, lifestyle changes, and in some cases, surgical interventions like implantable devices or heart transplant.


Arrhythmias refer to irregular heart rhythms that can range from harmless to life-threatening. These abnormal heart rhythms can cause symptoms such as palpitations, dizziness, fainting, or shortness of breath. Treatment options for arrhythmias may include medications, lifestyle modifications, implantable devices, or procedures like cardiac ablation.

Valvular heart disease

Valvular heart disease occurs when there is damage or dysfunction of the heart valves, which control the flow of blood through the heart. This can lead to symptoms such as fatigue, shortness of breath, and chest pain. Treatment options for valvular heart disease may involve medication, surgery to repair or replace the damaged valve, or minimally invasive procedures like transcatheter valve repair or replacement.


Cardiomyopathy is a condition that affects the heart muscle, making it harder for the heart to pump blood effectively.

Symptoms and Diagnosis of Heart Disease

Coronary angiography for heart disease diagnosis

Coronary angiography, also known as cardiac catheterization, is a diagnostic procedure used to visualize the coronary arteries and evaluate the presence of blockages or narrowing. This procedure provides detailed information about the condition of the arteries and helps guide treatment decisions.

Procedure overview

During coronary angiography, a thin tube called a catheter is inserted into a blood vessel, usually in the groin or arm. The catheter is then guided to the heart, and a contrast dye is injected to make the blood vessels visible on X-rays. This allows the healthcare professional to assess the presence, location, and severity of any coronary artery blockages.

Preparation for angiography

Before undergoing coronary angiography, you will be asked to refrain from eating or drinking for several hours. Medications that may interfere with the procedure may also need to be temporarily discontinued. Your healthcare provider will provide specific instructions on how to prepare for the procedure.

The angiography procedure

During the procedure, you will be awake but given medication to help you relax. The catheter is inserted into the blood vessel, and X-ray images are taken as the contrast dye is injected. You may experience a warm sensation as the dye is administered. The procedure typically takes about 30 minutes to an hour.

Risks and complications

While coronary angiography is generally considered safe, there are risks associated with any invasive procedure. These risks include bleeding, infection, allergic reactions to the contrast dye, blood vessel damage, and irregular heart rhythms. It is important to discuss the potential risks and benefits of coronary angiography with your healthcare provider before undergoing the procedure.

Clotting tests for heart disease diagnosis

Clotting tests are laboratory tests used to assess the ability of blood to clot and detect any abnormalities that may increase the risk of heart disease. These tests play a crucial role in diagnosing and managing certain heart conditions.

Prothrombin time (PT)

Prothrombin time measures how long it takes for blood to clot. It assesses the function of certain clotting factors in the blood, providing information about the body’s ability to form a clot. Abnormal PT results may indicate an increased risk of blood clots or bleeding disorders.

Activated partial thromboplastin time (aPTT)

Activated partial thromboplastin time measures how long it takes for blood to clot in a different pathway than PT. It helps evaluate the function of additional clotting factors, providing a comprehensive assessment of the blood’s clotting ability. Deviations from the normal range may signal an increased risk of bleeding or clotting disorders.

International normalized ratio (INR)

The international normalized ratio is a standardized measure used to interpret PT and ensure consistency across different laboratories. It is commonly used to monitor and adjust the dosage of anticoagulant medications like warfarin. Consistently elevated INR levels may indicate an increased risk of bleeding, while consistently low levels may suggest an increased risk of blood clots.

D-dimer test

The D-dimer test measures the presence of a substance called D-dimer in the blood. D-dimer is produced when blood clots are broken down. Elevated levels may indicate the presence of a blood clot, as seen in conditions like deep vein thrombosis, pulmonary embolism, or disseminated intravascular coagulation.

Symptoms and Diagnosis of Heart Disease
