Understanding the Heart and Its Function

The heart is a muscular organ with four chambers. The two upper chambers (atria) receive blood, and the two lower chambers (ventricles) pump blood out to the lungs and body. It works through a network of blood vessels and electrical signals that regulate heartbeats and circulation.

Main functions of the heart include:

• Delivering oxygen and nutrients to tissues
• Removing carbon dioxide and waste products
• Maintaining blood pressure and circulation
• Supporting organ function throughout the body

Any disruption in structure, blood flow, or rhythm can lead to cardiovascular disease.

Common Heart Conditions

Heart diseases are among the leading causes of death worldwide. Early awareness can significantly reduce complications.

Coronary Artery Disease (CAD)

Occurs when arteries supplying blood to the heart become narrowed due to plaque buildup.

Symptoms may include:

• Chest pain (angina)
• Shortness of breath
• Fatigue
• Heart attack in severe cases

Heart Attack (Myocardial Infarction)

Happens when a coronary artery is completely blocked, cutting off blood supply to heart muscle.

Warning signs include:

• Chest pressure or squeezing pain
• Pain radiating to the arm, neck, or jaw
• Sweating, nausea, dizziness

Immediate medical attention is critical.

Heart Failure

A chronic condition where the heart cannot pump enough blood to meet the body’s needs.

Common symptoms:

• Swelling in legs and feet
• Breathlessness while lying down
• Fatigue and reduced exercise tolerance

Arrhythmias (Irregular Heartbeats)

Electrical disturbances cause the heart to beat too fast, too slow, or irregularly.

Common types include atrial fibrillation, ventricular tachycardia, and bradycardia.

Heart Valve Disease

Heart valves may narrow (stenosis) or leak (regurgitation), affecting blood flow inside the heart.

Congenital Heart Defects

Structural heart abnormalities present from birth, ranging from minor to complex conditions.

Risk Factors for Heart Disease

Understanding risk factors helps prevent heart problems before they start.

Modifiable risk factors include:

• High blood pressure
• High cholesterol
• Smoking
• Diabetes
• Obesity
• Sedentary lifestyle
• Unhealthy diet
• Excess alcohol

Non-modifiable risk factors include:

• Age
• Family history
• Genetic predisposition
• Gender (men at higher risk earlier; women after menopause)

Managing lifestyle and medical conditions can significantly reduce heart disease risk.

Advanced Cardiac Diagnostics

Modern cardiology uses sophisticated tools to detect heart problems early and accurately.

Electrocardiogram (ECG/EKG)

Records the heart’s electrical activity to detect arrhythmias, heart attacks, and other abnormalities.

Echocardiography

An ultrasound of the heart that shows heart size, pumping strength, valve function, and blood flow patterns.

Types include 2D echo, Doppler echo, transesophageal echo (TEE), and 3D echo.

Stress Testing

Assesses heart function under physical or medication-induced stress. It helps detect blocked arteries, exercise tolerance, and rhythm issues.

Cardiac CT Scan

Provides detailed images of coronary arteries and heart structures and is used for calcium scoring and detecting blockages.

Cardiac MRI

Offers high-resolution images of heart muscle and blood flow. It is especially helpful in cardiomyopathies, congenital heart disease, and tissue damage assessment.

Coronary Angiography

A gold-standard diagnostic test where dye is injected into coronary arteries to detect blockages. It is often performed before angioplasty or bypass surgery.

Preventive Cardiology and Early Screening

Prevention is a cornerstone of cardiac care. Early detection saves lives.

Routine screening may include:

• Blood pressure monitoring
• Lipid profile (cholesterol test)
• Blood sugar testing
• Body mass index (BMI) evaluation
• Lifestyle assessment

Advanced preventive tools may include:

• Coronary calcium scoring
• Genetic risk screening
• Wearable heart monitors for rhythm tracking

Preventive cardiology helps reduce the likelihood of heart attacks, strokes, and heart failure.

From diagnosis to recovery, we’re here for your heart every step of the way.

Interventional Cardiology

Interventional cardiology uses catheters, imaging guidance, and specialized devices to treat heart disease without large surgical incisions.

Coronary Angioplasty

Also known as Percutaneous Coronary Intervention (PCI), this procedure opens blocked coronary arteries.

A thin catheter with a balloon is inserted through the wrist or groin and guided to the blocked artery. The balloon is inflated to widen the artery and restore blood flow.

Benefits include:

• Immediate relief from chest pain
• Reduced heart damage during a heart attack
• Short hospital stay
• Faster recovery compared to open surgery

Coronary Stenting

After angioplasty, a stent (a small metal mesh tube) is placed to keep the artery open.

Modern stent types include:

• Drug-eluting stents that release medication to prevent re-narrowing
• Bioresorbable stents that gradually dissolve over time

Rotational Atherectomy

Used for heavily calcified arteries, this technique uses a tiny rotating device to break down hard plaque before stenting.

Balloon Valvuloplasty

A catheter-based technique used to widen narrowed heart valves, especially in patients who are not suitable for open surgery.

Structural Heart Procedures

Advances in cardiology now allow treatment of heart valve and structural defects without open-heart surgery.

Transcatheter Aortic Valve Replacement (TAVR/TAVI)

A minimally invasive procedure to replace a narrowed aortic valve. The new valve is delivered via catheter, usually through an artery in the leg.

Ideal for:

• Elderly patients
• High-risk surgical patients

MitraClip for Mitral Regurgitation

A catheter-based device clips together parts of the mitral valve to reduce leakage, improving symptoms of heart failure.

Closure of Congenital Heart Defects

Small holes in the heart, such as Atrial Septal Defect (ASD) or Patent Foramen Ovale (PFO), can be closed using catheter-delivered devices without open surgery.

Cardiac Surgery

When catheter-based procedures are not sufficient, cardiac surgery provides definitive treatment for complex heart conditions.

Coronary Artery Bypass Grafting (CABG)

Also known as bypass surgery, this procedure creates a new pathway for blood to flow around blocked arteries using vessels from the leg or chest.

Modern advancements include:

• Off-pump bypass surgery (performed without stopping the heart)
• Minimally invasive bypass through small incisions

Heart Valve Surgery

Damaged valves may be repaired or replaced.

Options include:

• Mechanical valves (long-lasting, require lifelong blood thinners)
• Bioprosthetic valves (made from animal tissue, fewer medications needed)

Robotic and minimally invasive techniques now allow valve surgery with smaller incisions and quicker recovery.

Aortic Surgery

Treats aneurysms (bulging blood vessels) or dissections (tears in the aorta), which can be life-threatening if untreated.

Advanced Heart Rhythm Treatments

Heart rhythm disorders may require specialized procedures.

Catheter Ablation

A minimally invasive treatment that destroys small areas of heart tissue causing abnormal electrical signals. It is commonly used for atrial fibrillation and other arrhythmias.

Pacemakers

Implanted devices that regulate slow heart rhythms by sending electrical impulses to the heart.

Implantable Cardioverter Defibrillators (ICDs)

Devices that detect and correct life-threatening fast heart rhythms, preventing sudden cardiac death.

Cardiac Resynchronization Therapy (CRT)

Used in heart failure patients, CRT devices improve coordination between heart chambers, enhancing pumping efficiency.

Emergency Cardiac Care

Rapid response is crucial during heart emergencies.

Heart Attack Management
