The treatment goals for ischemic heart disease are to relieve symptoms, improve heart function, and reduce the risk of future cardiac events. Treatment strategies typically combine medications, surgery, and lifestyle adjustments to achieve long-term disease control. Physicians will develop personalized treatment plans based on the patient's age, severity of the disease, and complications.
The treatment process emphasizes the dual goals of "preventing recurrence" and "slowing disease progression." For example, medication can immediately relieve angina, while interventional surgery can directly open blocked coronary arteries. Additionally, active participation in lifestyle changes, such as quitting smoking and regular exercise, can significantly enhance treatment effectiveness. Most patients require long-term follow-up, with regular electrocardiograms or blood tests to assess treatment response.
Modern medicine offers a multi-faceted treatment strategy, primarily divided into three main parts: medication control, surgical intervention, and lifestyle adjustments. Medication treatment can be categorized into two main types: acute symptom relief and chronic disease progression delay. Surgical treatments include percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) to restore myocardial blood flow. Lifestyle adjustments form the foundation of treatment and should be implemented alongside medical measures.
Acute phase treatment focuses on dilating coronary arteries and dissolving blood clots. For instance, nitroglycerin is used for immediate relief of angina, while antiplatelet medications like aspirin inhibit thrombus formation during acute myocardial infarction. Chronic treatment emphasizes long-term control of risk factors, such as lipid-lowering medications to reduce the progression of atherosclerosis.
Nitrates (such as nitroglycerin) can dilate arteries and reduce the heart's oxygen demand, making them the first choice for acute angina. Beta-blockers (such as metoprolol) can lower heart rate and blood pressure, reducing myocardial oxygen demand while also having antiarrhythmic effects. Calcium channel blockers (such as amiodarone) are used in specific patients to control vascular contraction but should be used cautiously in patients with severe heart failure.
Lipid-lowering medications such as statins (atorvastatin, rosuvastatin) are the mainstay of treatment. Studies have shown that long-term use can reduce low-density lipoprotein (LDL-C) by 30-50% and also have anti-inflammatory and plaque-stabilizing effects. Antiplatelet medications (such as aspirin and clopidogrel) can inhibit platelet aggregation and reduce the risk of thrombus formation.
Emerging drugs like PCSK9 inhibitors target patients with refractory hyperlipidemia and can further reduce LDL-C by over 60%. Diuretics and ACE inhibitors are used in patients with concomitant heart failure to improve cardiac afterload and reduce hospitalization rates.
This procedure involves the use of a catheter to insert a balloon angioplasty or stent into the blocked coronary artery. The surgery is quick and minimally invasive, suitable for single-vessel blockages or patients with acute myocardial infarction. Modern drug-eluting stents can reduce the rate of restenosis but require dual antiplatelet therapy for at least one year.
Surgical risks include vascular puncture complications or thrombus formation within the stent, but the success rate exceeds 90%. Complex lesions may require the combination of rotational atherectomy or thrombectomy techniques to enhance blood flow restoration.
This open-heart surgery is suitable for patients with multi-vessel blockages or left main disease. The surgeon will take the patient's own veins or internal thoracic arteries to bypass the blockage and restore blood flow. Long-term studies have shown that this surgery has better prognoses for patients with poor left ventricular function.
Surgical risks include stroke or renal dysfunction, but the 5-year survival rate is better than that of untreated patients. Complex cases may require extracorporeal circulation support, and close monitoring of heart rhythm and renal function changes is necessary postoperatively.
Lifestyle adjustments are fundamental to treatment and can reduce the risk of recurrence by 40-50%. Quitting smoking can decrease the risk of cardiovascular events by 50%, as nicotine in tobacco induces coronary artery constriction. Dietary control should focus on low-fat, high-fiber principles, such as adopting a Mediterranean diet structure, with daily saturated fat intake below 10% of total calories.
Aerobic exercises like jogging or swimming for 150 minutes per week can enhance cardiac metabolic adaptability. In terms of stress management, mindfulness meditation has been shown to reduce blood pressure and cortisol levels, with a recommendation of 10-15 minutes daily. The weight management goal is to maintain a BMI of 22-25, with a 5% weight loss improving insulin resistance.
Gene therapy is under development, aiming to repair endothelial cell function or promote neovascularization. Among these, adeno-associated virus vectors delivering the VEGF gene have shown potential in animal studies to improve myocardial blood flow. In stem cell therapy, bone marrow mesenchymal stem cell transplantation can promote myocardial repair, but technical bottlenecks regarding cell survival and differentiation direction need to be addressed.
The application of artificial intelligence in treatment planning is gradually becoming widespread, with machine learning models capable of accurately predicting vascular blockage locations based on coronary angiography and biomarkers. Wearable devices such as continuous ECG monitors can detect abnormal heart rhythms in real-time and trigger alarm systems, potentially integrating into telemedicine platforms in the future.
Seek immediate medical attention when experiencing new-onset chest pain, resting angina, or worsening of existing symptoms. If patients continue to experience shortness of breath, lower limb edema, or unexplained fatigue after treatment, it indicates possible concurrent heart failure that requires reevaluation. Diabetic patients with three-vessel blockages should undergo coronary angiography follow-up every six months.
The following situations require medical attention within 24 hours:
Physicians will determine the treatment method based on the degree of vascular blockage, severity of symptoms, and overall health status of the patient. For mild blockages without acute symptoms, antiplatelet medications or vasodilators may be prioritized; if the vascular blockage exceeds 70% or if angina or myocardial infarction has occurred, coronary angioplasty or bypass surgery may be necessary. Regular assessments of cardiac function are key.
Do patients still need to continue medication control after surgery?Yes, the vast majority of patients will still require long-term use of antiplatelet medications, lipid-lowering drugs, or antihypertensive medications after surgery. Surgery only clears the blocked vessels but does not change the underlying atherosclerotic disease process. Regular monitoring of lipid levels, blood glucose, and blood pressure, along with medication, is crucial for controlling the condition.
What dietary principles are most effective in preventing disease progression?A low-salt, low-fat, and high-fiber diet structure is most recommended. It is advised to increase whole grains, deep-sea fish, and vegetables high in phytochemicals while limiting trans fats and refined sugars. The Mediterranean diet pattern, rich in Omega-3 and antioxidants, has been shown in studies to significantly reduce the risk of secondary events.
What is the mechanism of stress management in improving the condition?Psychological stress can lead to increased secretion of adrenaline, resulting in a faster heart rate and peripheral vascular constriction, increasing myocardial oxygen demand. Chronic stress can further promote inflammatory responses and thrombus formation, accelerating the progression of atherosclerosis. Relieving stress through mindfulness meditation or cognitive-behavioral therapy can indirectly reduce the risk of cardiovascular events.
How is exercise intensity assessed for patients undergoing cardiac rehabilitation?Rehabilitation physicians will assess the safe exercise range through cardiopulmonary function tests, initially focusing on walking or aquatic exercises, gradually increasing the intensity to 60-80% of the target heart rate. The exercise program must be adjusted according to the patient's medical history, and periodic stress testing should monitor progress to avoid excessive loads that may trigger angina.
