What is a Chronic Coronary Syndrome?

Chronic Coronary Syndrome refers to long-term coronary artery disease in which blood flow to the heart muscle is reduced, usually because of atherosclerotic narrowing of the coronary arteries. Symptoms may occur during physical activity or emotional stress and improve with rest, although some people may have few or no symptoms. The condition can change over time, so regular cardiovascular assessment and risk-factor management are important.

What is the Importance of Timely Treatment?

Timely treatment can help control chest discomfort and other symptoms, improve cardiovascular function when necessary, reduce the risk of heart attack and heart failure, and slow the progression of coronary artery disease. Regular assessment also helps determine whether lifestyle changes, medicines, or coronary revascularisation may be appropriate.

What are the Common Symptoms of Chronic Coronary Syndrome?

  • Chest Discomfort: Pressure, tightness, heaviness, or squeezing in the chest, often occurring during physical activity or emotional stress.
  • Shortness of Breath: Breathlessness may develop during exertion when the heart cannot receive enough oxygen-rich blood.
  • Fatigue: Some people experience unusual tiredness or reduced ability to perform routine physical activities.
  • Pain in Other Areas: Discomfort may spread to the arm, shoulder, neck, jaw, back, or upper abdomen.
  • Reduced Exercise Tolerance: Activities that were previously comfortable may cause tiredness, breathlessness, or chest discomfort.
  • Palpitations or Dizziness: Some patients may feel their heartbeat, lightheadedness, or weakness.

Causes and Risk Factors of Chronic Coronary Syndrome

Causes

  • Coronary Atherosclerosis: Plaque buildup may narrow coronary arteries and reduce blood supply to the heart muscle.
  • Coronary Artery Spasm: Temporary tightening of a coronary artery can reduce blood flow.
  • Coronary Microvascular Dysfunction: Abnormal function of small coronary blood vessels may contribute to chest pain or myocardial ischaemia, even without major obstructive coronary disease.
  • Other Coronary Abnormalities: Less common coronary conditions can also affect blood flow.

Risk Factors

  • Increasing age
  • High blood pressure
  • High LDL cholesterol
  • Diabetes
  • Smoking or tobacco exposure
  • Overweight or obesity
  • Physical inactivity
  • Unhealthy diet
  • Family history of premature coronary artery disease
  • Chronic kidney disease

Latest Research and Technologies in the Treatment of Chronic Coronary Syndrome in Thailand

  • Advances in chronic coronary syndrome management include improved coronary imaging, physiological assessment of coronary narrowing, and more targeted evaluation of patients with persistent chest pain despite no major obstructive coronary disease. Invasive physiological assessment and coronary function testing may also help guide treatment in appropriate patients. Research continues to focus on coronary microvascular dysfunction, vasospastic angina, and ischaemia with non-obstructive coronary arteries (INOCA).

Treatment options for Chronic Coronary Syndrome

Angioplasty (PCI) : PCI in Chronic Coronary Syndrome is an excellent option for maximising symptom relief and quality of life when optimal medical therapy fails to control angina.

Coronary Artery Bypass Grafting (CABG) : Surgical revascularisation is used for complex, multivessel, or left main anatomy to improve long-term survival.

  • Clinical assessment:
    • Medical History: Assessment of chest discomfort, symptom pattern, exercise tolerance, cardiovascular risk factors, previous cardiac events and medications.
    • Physical Examination: Evaluation of blood pressure, heart rate and relevant cardiovascular findings.
    • Electrocardiogram (ECG): Assesses heart rhythm and may identify evidence of ischaemia or previous myocardial injury.
    • Blood Tests: Lipid profile, glucose, HbA1c and kidney function. Cardiac troponin is used when an acute coronary event is suspected.
    • IVUS: Provides detailed images from inside the coronary artery during selected interventions.
    • OCT: Provides high-resolution images of coronary plaque and stents during selected procedures.
    • FFR/iFR: Physiological measurements can help determine whether a coronary narrowing significantly affects blood flow.
  • Imaging Tests:
    • CT Coronary Angiography: Provides detailed images of coronary anatomy and atherosclerotic plaque.
    • Coronary Angiography: An invasive test used to define coronary narrowing and guide revascularisation when indicated.
    • Echocardiography: Evaluates heart structure, pumping function, and regional wall motion.
    • Stress Echocardiography: Assesses heart function during exercise or pharmacological stress and may identify areas affected by reduced blood flow.
    • Cardiac MRI: Provides detailed information about cardiac structure, function, myocardial viability, and scarring in selected patients.
    • Nuclear Cardiac Imaging: May assess myocardial perfusion and identify areas with reduced blood flow.

Frequently Asked Questions

Chronic Coronary Syndrome is generally a long-term condition requiring ongoing management rather than a one-time recovery period. Recovery after angioplasty or CABG varies by procedure and individual health, while medicines, lifestyle changes, and cardiovascular follow-up may continue long-term.

Many people with stable Chronic Coronary Syndrome can walk and remain physically active. The right level of activity depends on symptoms, heart function, and disease severity, so a healthcare professional should guide exercise when symptoms or significant disease are present.

Many advanced Thai cardiac centres offer CT coronary angiography, coronary angiography, stress testing, echocardiography, IVUS, OCT, FFR/iFR, angioplasty, modern stents, CABG, and cardiac rehabilitation.

Many major Thai hospitals have international patient departments that help overseas patients with medical records, appointments, treatment coordination, accommodation, interpretation (where available), and follow-up arrangements.

Look for a centre with experienced cardiologists and interventional cardiologists, advanced coronary imaging, catheterisation facilities, cardiac surgery when needed, intensive cardiac care, and cardiac rehabilitation. Complex cases may benefit from multidisciplinary treatment planning.

The outcomes depend on the severity of coronary disease, symptoms, heart function, other medical conditions, and the treatment used. Appropriate medical management, lifestyle measures, and revascularisation when indicated can improve symptoms and cardiovascular outcomes in suitable patients.

Many Thai cardiac centres have cardiologists, interventional cardiologists, and cardiac surgeons experienced in managing chronic coronary disease through medical therapy, PCI, CABG, and comprehensive cardiovascular care.

Risks depend on the treatment used. Medicines may cause side effects, while angioplasty and stenting can involve bleeding, blood-vessel injury, contrast reactions, or, rarely, serious cardiac complications. CABG carries risks such as bleeding, infection, rhythm disturbances, stroke, kidney complications, and anaesthesia-related complications.

Chronic coronary syndrome is a cardiovascular condition, not an injury. New or severe chest pressure, breathlessness, cold sweating, fainting, nausea or pain spreading to the arm, jaw or back may indicate a heart attack. Seek emergency medical attention immediately, even if symptoms improve.

Chronic coronary syndrome is a cardiovascular condition, not an injury. New or severe chest pressure, breathlessness, cold sweating, fainting, nausea or pain spreading to the arm, jaw or back may indicate a heart attack. Seek emergency medical attention immediately, even if symptoms improve.

Chronic coronary syndrome does not directly cause physical or skeletal deformities. However, severe coronary disease or complications such as a heart attack or heart failure may reduce exercise capacity and cause long-term functional limitations. Appropriate treatment and individualised cardiac rehabilitation may help maintain or improve daily functioning.

Yes. Untreated or poorly controlled Chronic Coronary Syndrome can worsen symptoms and increase the risk of heart attack, heart failure, abnormal heart rhythms, and other cardiovascular complications.

You can reduce cardiovascular risk by avoiding tobacco, controlling LDL cholesterol and blood pressure, managing diabetes, following a heart-healthy diet, maintaining a healthy weight, staying physically active within medically appropriate limits, and taking prescribed medicines. Regular cardiovascular assessment is particularly important for people with established coronary disease or multiple risk factors.

Yes. Risk is higher with increasing age, high LDL cholesterol, high blood pressure, diabetes, smoking, obesity, physical inactivity, chronic kidney disease, and a family history of premature coronary artery disease.
