What is an Acute Coronary Syndrome?

Acute Coronary Syndrome occurs when blood flow through a coronary artery suddenly decreases or stops, most commonly because an atherosclerotic plaque ruptures or erodes and a blood clot forms. Depending on the severity and duration of reduced blood flow, ACS may present as unstable angina, NSTEMI, or STEMI. ACS is a medical emergency that requires prompt evaluation and treatment.

What is the Importance of Timely Treatment?

Timely treatment is crucial as the heart muscle can be irreversibly damaged by excessive blood flow interruption. Fast diagnosis, ECG assessment, appropriate medication, and restoring coronary blood flow when possible can limit myocardial damage, reduce complications, and improve survival. Call for emergency help without delay as soon as ACS is suspected.

What are the Common Symptoms of an Acute Coronary Syndrome?

  • Chest Pain or Discomfort: Pressure, squeezing, heaviness, tightness, or burning in the chest that may occur at rest or with activity.
  • Pain in Other Areas: Discomfort may spread to the arm, shoulder, neck, jaw, back, or upper abdomen.
  • Shortness of Breath: Breathlessness may occur with or without chest discomfort.
  • Cold Sweating: Sudden sweating may accompany acute cardiac ischemia.
  • Nausea or Vomiting: Gastrointestinal symptoms can occur, particularly during a heart attack.
  • Dizziness or Fainting: Reduced cardiac function or abnormal heart rhythms may cause lightheadedness, weakness, or loss of consciousness.

Causes and Risk Factors of Acute Coronary Syndrome

Causes

  • Plaque Rupture or Erosion: Atherosclerotic plaque can rupture or erode, triggering formation of a blood clot inside a coronary artery.
  • Coronary Blood Clot: A thrombus can suddenly restrict or completely block coronary blood flow.
  • Coronary Artery Spasm: Severe temporary narrowing of a coronary artery can reduce blood supply to the heart.
  • Coronary Artery Dissection: A tear within the coronary artery wall can obstruct blood flow.
  • Severe Coronary Narrowing: Advanced coronary artery disease can contribute to acute ischemia.

Risk Factors

  • Increasing age
  • High blood pressure
  • High LDL cholesterol
  • Diabetes
  • Smoking or tobacco use
  • Obesity
  • Physical inactivity
  • Unhealthy diet
  • Family history of premature coronary artery disease
  • Chronic kidney disease
  • Previous coronary artery disease or heart attack

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

  • Advances in acute coronary syndrome management focus on rapid diagnosis, timely restoration of coronary blood flow, appropriate antithrombotic treatment, and prevention of recurrent cardiovascular events. Research and clinical practice also focus on radial-access PCI, complete revascularisation in appropriate patients, and mechanical circulatory support for selected patients with severe haemodynamic instability. Rapid STEMI referral networks and structured secondary prevention are important components of care.

Treatment options for Acute Coronary Syndrome

Percutaneous Coronary Intervention (PCI): Coronary angiography followed by angioplasty and stent placement may rapidly restore blood flow, particularly in patients with STEMI or selected high-risk ACS.

Coronary Artery Bypass Grafting (CABG) : CABG may be considered when coronary anatomy is unsuitable for PCI or when extensive or complex disease requires surgical revascularisation.

  • Clinical assessment:
    • Medical History: Assessment of chest pain characteristics, onset, duration, associated symptoms, previous heart disease, medications, and cardiovascular risk factors.
    • Physical Examination: Evaluation of blood pressure, heart rate, oxygen saturation, circulation, and signs of heart failure or shock.
    • Electrocardiogram (ECG): Perform a 12-lead ECG promptly to identify ST-segment elevation and other signs of acute myocardial ischemia.
    • High-Sensitivity Cardiac Troponin: Serial troponin measurements help identify myocardial injury and support diagnosis of myocardial infarction.
    • Blood Tests: Complete blood count, kidney function, electrolytes, glucose, lipid profile, and other tests may be performed based on the clinical situation.
    • Continuous ECG Monitoring: Monitoring helps detect potentially dangerous arrhythmias during acute care.
  • Imaging Tests:
    • Coronary Angiography: Defines the location and severity of coronary blockage and allows treatment planning during PCI.
    • Echocardiography: Assesses heart pumping function, regional wall-motion abnormalities, and complications.
    • CT Coronary Angiography: May be considered in selected patients when ACS is not clearly established, and invasive angiography is not immediately required.
    • Cardiac MRI: Can help evaluate myocardial injury and distinguish certain causes of acute chest pain in selected cases.
    • Chest X-Ray: May help assess alternative causes of symptoms or complications such as pulmonary congestion.
    • IVUS: Provides detailed images from inside the coronary artery during selected interventions.
    • OCT: Provides high-resolution images of plaque, thrombus, and stents during selected coronary procedures.

MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services designed to support Acute Coronary Syndrome patients in Thailand. These services include:

  • Cardiac Rehabilitation: Structured rehabilitation can support physical recovery and reduce future cardiovascular risk.
  • Gradual Physical Activity: Increase activity progressively based on heart function, symptoms, and medical advice.
  • Medicines used in acute coronary syndrome may include aspirin and other antiplatelet medicines, anticoagulants, statins or other lipid-lowering therapies, nitrates, beta-blockers and medicines to manage heart failure or other associated conditions. The choice of treatment depends on the type of ACS, haemodynamic status, coronary findings, bleeding risk, kidney function and other medical conditions.

Frequently Asked Questions

Recovery varies according to whether the patient had unstable angina, NSTEMI, or STEMI, as well as the extent of heart damage and treatment received. Recovery after an uncomplicated angioplasty may be relatively quick, while recovery after a major heart attack or CABG can take several weeks to months.

During an active Acute Coronary Syndrome, avoid physical activity and seek emergency medical care. After stabilisation, doctors usually reintroduce walking gradually under medical guidance, often as part of cardiac rehabilitation.

Many advanced Thai cardiac centres provide emergency ECG and cardiac biomarker testing, coronary angiography, PCI, modern drug-eluting stents, echocardiography, intensive cardiac care, and cardiac rehabilitation. Selected centres may also offer IVUS, OCT, and other advanced coronary technologies.

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. However, suspected ACS requires immediate local emergency care, not delayed treatment for international travel.

For ACS, prioritise a hospital with emergency cardiac services, rapid ECG and troponin testing, a catheterisation laboratory, experienced interventional cardiologists, coronary care or intensive-care facilities, and cardiac surgery when required.

Outcomes depend on the type of ACS, time from symptom onset to treatment, the location and severity of the blockage, heart function, age, and other medical conditions. Early recognition and timely reperfusion, when indicated, are key to improving outcomes.

Many Thai cardiac centres have cardiologists, interventional cardiologists, and cardiac surgeons experienced in emergency management of heart attacks and other acute coronary syndromes, including PCI and CABG when indicated.

Risks depend on the condition and treatment. Antiplatelet and anticoagulant medicines can increase bleeding risk, while angiography and PCI may involve bleeding, blood-vessel injury, contrast reactions, arrhythmias, or rarely serious cardiac complications. Fibrinolytic therapy carries a risk of major bleeding, and CABG involves surgical risks such as infection, bleeding, stroke, kidney complications, and anaesthesia-related complications.

Acute coronary syndrome is a medical emergency. If you experience new or severe chest pressure, breathlessness, cold sweats, nausea, fainting, or pain spreading to the arm, jaw, back, or shoulder, call emergency medical services immediately. Do not drive yourself or wait for symptoms to settle.

ACS does not directly cause physical or skeletal deformities. However, a major heart attack or complications such as heart failure, stroke or prolonged critical illness may lead to lasting limitations in physical function. Recovery depends on the extent of damage, complications and rehabilitation.

Yes. An acute coronary event may affect exercise capacity, daily activities, emotional well-being, and confidence about future health. Appropriate treatment, cardiac rehabilitation, lifestyle changes, and long-term cardiovascular follow-up can help many patients regain functional capacity and reduce future risk.

Yes. Untreated ACS can rapidly cause permanent heart muscle damage and may lead to life-threatening complications such as dangerous arrhythmias, heart failure, cardiogenic shock, or cardiac arrest. Immediate medical assessment is essential.

You can reduce risk by avoiding tobacco, controlling LDL cholesterol and blood pressure, managing diabetes, maintaining a healthy weight, following a heart-healthy diet, staying physically active when medically appropriate, and taking prescribed medicines.

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. People with existing coronary artery disease or a previous heart attack are also at increased risk.
