The heart is the center of life—the place where every beat, emotion, and moment of existence originates. When blood vessels nourishing the heart narrow, all those precious things become fragile.
Coronary heart disease (CHD) is more than just a medical diagnosis. It is a profound warning about the silent wear and tear inside the body. It erodes endurance, suffocates the breath, and shakes even the most normal moments.
Understanding CHD is the first step to regaining control of your own heart.
CHD is caused by plaque buildup in coronary arteries.
What Is CHD (Coronary Heart Disease)?
Coronary artery disease (CHD) is the most obvious manifestation of long-term damage within the cardiovascular system. Every beat is threatened by the silent but persistent accumulation of atherosclerotic plaque in the coronary arteries. When the lumen of the artery narrows, the heart is no longer nourished with enough oxygen-rich blood, which begins a series of survival consequences. CHD is not an abstract concept but a clinical entity in millions of bodies daily, every hour.
Pathology
CHD occurs when the endothelium of the coronary arteries is damaged, leading to inflammation and the formation of atherosclerotic plaques. These plaques thicken over time, causing blockage of blood circulation to the heart muscle, reducing contractility, and creating conditions for angina or myocardial infarction.
Effects on the cardiovascular system
Reduced blood flow to the heart causes the heart muscle to lack oxygen, leading to arrhythmia, heart failure, and increased risk of death. Each contraction becomes heavy, tired, and fragile under physiological and emotional pressure.
Distinguishing characteristics
CHD is a specific form of heart disease, focusing mainly on damage to the coronary arteries - the blood vessels that feed the heart. It is different because of its insidious nature, the ability to progress silently but flare up violently when it exceeds the body's tolerance threshold.
Causes of CHD
Coronary artery disease does not occur randomly. It is the result of a long-term accumulation of biological and lifestyle risk factors – agents that gradually erode the vessel wall and deform the circulatory system when the body is drawn into a chain of inflammatory reactions, metabolic disorders, and endothelial cell damage, a coronary storm begins to smolder quietly but extremely dangerously.
Atherosclerosis
The accumulation of cholesterol plaque inside the vessel lumen is the main cause of coronary artery narrowing and hardening. This process starts with small lesions in the vessel wall and develops into an obstruction of blood flow to the heart.
Hypertension and dyslipidemia
High blood pressure puts constant pressure on the vessel walls, making them weak and vulnerable. At the same time, high levels of bad cholesterol (LDL) promote the deposition of blood fat in the vessel lumen.
Diabetes and Insulin Resistance
Dysglycemia alters vascular tissue structure, disrupts homeostasis, and increases systemic inflammation, which promotes the spread of atherosclerosis.
Smoking and toxins
Nicotine, carbon monoxide, and hundreds of toxic compounds in cigarette smoke are catalysts that disrupt endothelial function, promote vasoconstriction, and cause thrombosis.
Chronic inflammation
Slow-burning inflammation, whether caused by obesity, stress, or underlying infection, is a key factor in increasing endothelial reactivity and activating autoimmune destruction that leads to coronary artery damage.
Symptoms of CHD
The human body sends out signals when life is in danger – and coronary artery disease is one of those conditions that send messages in clear but easily ignored language. The symptoms of CHD are a combination of oxygen deprivation, circulatory disturbances, and heart muscle dysfunction, manifesting in a range of sensations, from vague aches to clear physical crises.
Angina
A squeezing, heavy, or burning sensation in the chest, often radiating to the left arm, shoulder, neck, or jaw. The pain often occurs during exertion, strong emotions, or after a big meal – when the oxygen demand is high, but the coronary arteries cannot meet it.
Shortness of breath and fatigue
Feeling short of breath, gasping for breath even with light exercise. This is a manifestation of reduced oxygen-rich blood flow to the heart muscle and other organs, causing the entire body to fall into exhaustion.
Rapid, palpitations
The heart rate becomes unstable, possibly abnormally fast, or arrhythmia. This is the heart's response to compensate for the lack of blood supply and the disordered electrical signals.
Silent CHD
Some people have CHD without typical symptoms until a major event such as a heart attack occurs - when the body sounds the final warning bell.
Complications of CHD
Coronary artery disease does not stop at transient angina. When the heart's blood vessels are damaged, the entire cardiovascular system is caught in a spiral of deterioration, decompensation, and collapse. Complications of CHD are irreversible consequences, threatening lives every minute and every second. Each complication is a door leading to total collapse - both physically, functionally, and in terms of life expectancy.
Myocardial infarction (heart attack)
A ruptured plaque can form a blood clot that completely blocks the coronary artery. The part of the heart muscle behind the blockage will die due to lack of blood, causing severe chest pain, sweating, nausea, dizziness, and possibly death if not intervened promptly.
Heart failure
The heart loses its ability to contract effectively, leading to circulatory congestion, pulmonary edema, chronic fatigue, and a severe reduction in quality of life. This is a long-term consequence of myocardial damage due to prolonged ischemia.
Arrhythmias
Electrical damage to the conduction system causes atrial fibrillation, ventricular fibrillation, or paroxysmal tachycardia. These disorders can lead to cardiac arrest if left unchecked.
Sudden Death
CHD is the leading cause of sudden death in adults. Cardiac arrest occurs suddenly, without warning, and can have devastating consequences if not treated within the first few minutes.
How CHD Is Diagnosed
Diagnosis of coronary artery disease is a multi-layered process, combining clinical experience, imaging data, and sophisticated biological indicators. The disease does not reveal itself through a single sign but is hidden under a complex shell of symptoms, risk factors, and microscopic changes inside the blood vessels. Identifying CHD requires harmonious coordination between doctors and modern medical technology - tracing each abnormal heart signal.
Clinical examination and medical history
The doctor carefully exploits symptoms and assesses family history, lifestyle habits, and risk factors such as high blood pressure, diabetes, and smoking. This is the foundation for appropriate paraclinical orientation.
Electrocardiogram (ECG)
ECG records the heart's electrical activity, detecting signs of myocardial ischemia, arrhythmia, or old damage. It is a rapid, popular diagnostic tool with strong suggestive value.
Echocardiography and stress testing
Ultrasound assesses myocardial motion and function. Stress testing monitors the cardiac response to exercise, which is a time when transient ischemia due to coronary stenosis is most likely to be detected.
Coronary angiography (CT or DSA)
Advanced imaging techniques allow direct observation of coronary artery stenosis, occlusion, calcification, or deformation. This is the gold standard for diagnosing CHD and guiding therapeutic interventions.
Treatment Options for CHD
Coronary artery disease treatment involves a comprehensive journey of clinical medicine, lifestyle modifications, and high-tech interventions. The goal is to control symptoms, restore circulation, preserve the heart muscle, and prevent disease progression. Each treatment option is a key link in the heart's survival chain.
Lifestyle changes
An anti-inflammatory diet rich in green vegetables, whole grains, and unsaturated fats helps lower cholesterol and blood pressure. Regular exercise increases blood flow and improves endothelial function. Quitting smoking immediately reduces the risk of coronary events. Stress management, adequate sleep, and weight control are integral.
Medication
Statins lower blood lipids and stabilize plaques. Beta-blockers reduce the burden on the heart and limit angina. Aspirin prevents blood clots. ACE inhibitors improve blood pressure and heart function.
Interventions – Surgery
Angioplasty and stenting widen the narrowed area to restore blood flow. Coronary artery bypass grafting (CABG) creates a new blood pathway, protecting the ischemic heart muscle and reducing the risk of recurrent myocardial infarction.
Preventing Coronary Heart Disease
Preventing coronary heart disease does not start in the hospital but in your daily life. When every choice in life, nutrition, and emotion directly affects the cardiovascular system, proactively protecting the coronary arteries becomes an essential action that cannot be delayed. Preventing CHD means protecting life from the inside, every cell, every blood vessel, and every breath.
Cardiovascular Nutrition
Foods rich in fiber, antioxidants, and omega-3 fatty acids help clean the arteries, regulate blood lipids, and reduce inflammation. Green leafy vegetables, berries, fatty fish, and whole grains should appear regularly in meals.
Increase exercise
Aerobic exercise for 30 to 45 minutes daily helps improve circulation, increase blood vessel elasticity, and stabilize heart rate. Regular exercise also helps control weight and blood sugar.
Control blood pressure and blood lipids
Regular blood pressure and lipid testing help detect risks early and make timely adjustments. Preventive medication should be used as prescribed.
Eliminate risk factors
Avoid exposure to tobacco smoke, reduce alcohol consumption, and learn to manage stress to maintain coronary artery health. Quality sleep and a positive attitude are core to a comprehensive disease prevention strategy.
Living with CHD
Living with CHD is a process of rebuilding life at a different pace – slower, more conscious, and more disciplined. After diagnosis, every action carries the weight of survival. Life does not stop but is re-established with great caution and initiative. Every day becomes an opportunity to protect the heart, slow the progression of the disease, and improve the quality of life.
Daily management
Regularly monitoring blood pressure, heart rate, weight, and blood sugar helps control risk factors. Recording symptoms and maintaining a health diary creates a clear picture of disease progression.
Adherence to treatment
Taking medication on time, in the right dose, according to professional instructions ensures optimal effectiveness and minimizes complications. Regular check-ups help adjust the regimen to clinical developments.
Participate in cardiac rehabilitation
Rehabilitation programs that combine exercise, nutrition counseling, and psychotherapy help improve physical and mental health. They are a strategic step in long-term CHD management.
Maintain mental health
A positive attitude, stress management, and building supportive relationships are essential to keeping one's heart healthy—not just physically but emotionally as well.
