Currently, the incidence of coronary heart disease (CHD) is increasing year by year, and the number of patients with CHD is predicted to increase in conjunction with the aging process of our population. In the face of a potentially large patient population, we clinicians are required to stand taller and effectively perform our duties in the prevention and control of coronary heart disease. The unique pathophysiological mechanism of coronary artery disease and the emergence of evidence-based medicine in recent years have made the prevention and control of coronary artery disease more purposeful and rigorous. First of all, most coronary heart disease has a cause, and it is important to stifle the occurrence and limit the development of the disease from the source. It is a universal grand prescription for the prevention and control of coronary heart disease. In fact, the phrase is a healthy lifestyle, which for patients is a therapeutic lifestyle intervention. Unhealthy lifestyle behaviors can breed numerous irreversible risk factors for coronary heart disease, and the presence of these risk factors can promote coronary heart disease or equate to coronary heart disease. For example, high salt diet, unbalanced diet, low intake of fruits and vegetables, lack of physical strength or physical activity, smoking, alcohol abuse, irregular work and rest, and unbalanced or impatient moods are all considered unhealthy lifestyle behaviors. As time goes by, hypertension, hyperlipidemia, diabetes and other metabolic abnormalities that accompany them will creep up on us. And hypertension, hyperlipidemia and diabetes become the initiating link of coronary heart disease. It is clear that the prevention and control of coronary heart disease should undoubtedly start from defending a healthy lifestyle. The treatment of hypertension, dyslipidemia and diabetes is already a mending of the fold. However, it is not too late to achieve the early detection, early treatment and early achievement of hypertension, hyperlipidemia and diabetes mellitus. Second, the treatment of risk factors for coronary heart disease should be equal to the treatment of coronary heart disease. The detection of one risk factor needs to be evaluated for other risk factors, and intervention of these risk factors together can reduce the overall risk of coronary heart disease; the intervention of risk factors needs to evaluate the clinical situation of important organ functions (heart, brain, kidney, peripheral vascular), and prevention is the foresight to choose the medication for treatment; the majority of risk factors is equivalent to the risk group, and the treatment should strengthen the management of patients at the same time. Close follow-up, so that patients get a good healthy lifestyle, the prevention and control work in practice. Finally, the arrival of cardiovascular events should be faced rationally. Early intensive drug therapy (antithrombotic, statin and lipid-lowering therapy) is the core of controlling cardiovascular events, preventing their recurrence and reducing their consequences. Interventional therapy is better than drug therapy in improving symptoms, and timely interventional therapy is a powerful weapon in the treatment of coronary heart disease, which is no longer in doubt. However, interventional therapy must be closely combined with drug therapy in order to complement each other. Therefore, interventional therapy is conditional, and the conditions are clinical symptoms that cannot be controlled by drug therapy or special groups of patients who clearly outperform drug therapy (patients with acute myocardial infarction, patients with myocardial infarction combined with cardiogenic shock); the success of interventional therapy is temporary, and most of them are incomplete hemodynamic reconstruction treatment modes, which need drug therapy to maintain, consolidate and supplement. Of course, interventional therapy is convenient and minimally invasive, and patients can be followed up closely on the basis of pharmacological therapy and then undergo interventional therapy at an optional stage if necessary. Another treatment modality for revascularization is surgical treatment (coronary artery bypass grafting), which can be used for patients who are at high risk of intervention and have poor prognosis or are not suitable for intervention, and for whom drug therapy alone is not effective. In general, these three treatment options for coronary artery disease are consistent in terms of overall population prognosis.
