Overview

Title: Understanding and Managing Acute Coronary Syndrome: A Comprehensive Guide

Overview:

Acute Coronary Syndrome (ACS) is a clinical syndrome caused by acute myocardial ischemia, encompassing conditions such as unstable angina (UA), non-ST elevation myocardial infarction (NSTEMI), and ST elevation myocardial infarction (STEMI). This article delves into the diagnosis, treatment, and prevention strategies for ACS, highlighting key risk factors and lifestyle modifications that can help mitigate the condition.

Diagnosis:

The diagnosis of ACS involves a thorough evaluation of symptoms and clinical signs, including:

• Symptoms: Persistent chest pain, often described as闷胀、压迫感、紧缩感、烧灼感，or a sense of impending doom, which may radiate to other areas and be accompanied by sweating, nausea, vomiting, palpitations, or dyspnea. These symptoms may not be typical in elderly females or diabetics.
• Clinical Signs: Hypertension, tachycardia, diaphoresis, gallops, and systolic murmurs over the apex.
• Investigations: Blood tests, including complete blood count, renal and liver function tests, electrolytes, lipid profile, blood glucose, coagulation profile, and infectious disease screening. Cardiac biomarkers like troponin and creatine kinase-MB are also crucial.
• Imaging: Electrocardiogram (ECG), 24-hour Holter monitoring, stress tests, echocardiography, coronary angiography, intravascular ultrasound, optical coherence tomography, brain natriuretic peptide, D-dimer, erythrocyte sedimentation rate, C-reactive protein, chest X-ray, and radionuclide scans.

Treatment:

The management of ACS is categorized into three risk levels: low, moderate, and high. Key treatment modalities include:

• General Treatment: Bed rest, anxiety management, and oxygen therapy if needed. Lifestyle modifications and dietary changes are emphasized, including a high-fiber diet, omega-3 fatty acids, and antioxidants.
• Medications: Anti-anginal agents (e.g., nitrates), antiplatelet agents (e.g., aspirin, ADP receptor inhibitors), anticoagulants (e.g., heparin), and statins. ACE inhibitors or ARBs may also be prescribed.
• Revascularization: Percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) may be necessary in selected cases.
• Traditional Chinese Medicine: Herbs like Danshen, Chuanxiong, and Honghua are used for活血化瘀 (blood circulation and removal of blood stasis).

Prevention:

Prevention of ACS can be categorized into three levels:

• Primary Prevention: Lifestyle modifications for individuals at risk of developing ACS.
• Secondary Prevention: Medications and lifestyle changes for individuals with established ACS.
• Tertiary Prevention: Preventing complications and improving quality of life in ACS survivors.

Lifestyle Modifications:

• Diet: A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats.
• Exercise: Regular physical activity, such as walking, swimming, or cycling.
• Smoking Cessation: Avoiding smoking and secondhand smoke exposure.
• Stress Management: Techniques such as meditation, yoga, or deep breathing exercises.
• Regular Health Check-ups: Monitoring blood pressure, cholesterol, and blood sugar levels.

Conclusion:

Acute Coronary Syndrome is a serious condition that requires prompt diagnosis and appropriate management. By adopting a healthy lifestyle, managing risk factors, and seeking timely medical attention, individuals can significantly reduce their risk of ACS and improve their overall cardiovascular health.
