Description
Summary:In patients with ST-elevation myocardial infarction, immediate coronary angiography and intervention is the best practice, if an experienced laboratory is available. In non-Q-wave infarction most, but not all, studies suggest that early invasive strategy is superior to conservative management. Complete revascularization is preferred. A literature search regarding management of coronary artery disease was conducted in PubMed between January 1985 to January 2021. Articles published in English were reviewed, and those relevant were selected by both authors. Special focus was on the ISCHEMIA trial and related articles. The utility of coronary angiography in patients with stable coronary artery disease is challenging. All patients should undergo optimal medical therapy. Patients with angina should not only receive approved anti-anginal agents but should also receive lifestyle modifications and pharmacologic therapy to control risk factors such as diabetes, hypertension, dyslipidemia, and smoking; and should consider organized physical activity programs. Low density lipoprotein should be reduced to 70 mg/dL or less. Non-invasive studies such as coronary computed tomography angiography (CCTA) are preferred. If expert CCTA is not available, then stress test, preferably with imaging, is recommended. If the results of CCTA show high risk, then coronary angiography and intervention are usually indicated. In patients with left main disease, left ventricular dysfunction, or symptoms of congestive heart failure, early invasive strategy is recommended. If none of these conditions exist, then initial medical therapy may be initiated, and invasive therapy should be utilized only if clinically indicated. In patients with chronic stable angina, continue with medical therapy and risk factor modification. If the frequency or severity of angina episodes change, coronary angiography and revascularization should be considered, as appropriate. In patients with significant renal dysfunction, angiogram may be indicated only if there is complete failure of medical therapy. Optimal medical therapy should be initially utilized in all patients. Early invasive management and revascularization should be utilized in patients with left ventricular dysfunction, congestive heart failure, and failure of medical therapy. A shared decision-making process should always be utilized.
