Chest Paincp Is A 64 Year Old Male Who Presents To the Emergency Depar

Chest Pain CP is a 64-year-old male who presents to the emergency department (ED) via ambulance for chest pain. He was out shoveling snow from his driveway when he developed left anterior chest pain, pressure-type, radiating to his jaw and shoulder. Despite the cold weather, he was sweating. He also noted palpitations and shortness of breath, although he thought it was just because he was “a little out of shape.” He was afraid that something was wrong, so he asked his wife to call 911. His medical history includes hypertension, hyperlipidemia, diabetes mellitus, and gout. He is on hydrochlorothiazide and allopurinol. Socially, he is a retired factory worker, smokes one pack of cigarettes daily, and consumes about six beers daily. Physical examination reveals an obese man in moderate distress, with elevated blood pressure (172/110), and a regular pulse. Lung auscultation shows bilateral wheezes; cardiac examination notes a grade II/VI systolic murmur. Labs show mild leukocytosis, hypokalemia (K+ 2.9 mEq/L), hyperglycemia (glucose 252 mg/dL), elevated troponin (1.7 ng/L), and hyperuricemia (uric acid 11.1 mg/dL). The EKG exhibits ST segment depression with T-wave inversion over lateral leads. The working diagnosis includes non-ST segment elevation acute coronary syndrome (NSTE-ACS), hypertension, diabetes, obesity, alcohol use, hyperuricemia, and smoking.

Management of acute chest pain, especially in patients with underlying cardiovascular risk factors, requires prompt and targeted therapeutic interventions to reduce morbidity and mortality. The three key questions—what medications to initiate, which to continue post-discharge, and recommended lifestyle modifications—are integral to comprehensive care for this patient presenting with non-ST segment elevation acute coronary syndrome (NSTEMI).

1. Medications to be instituted for chest pain

Initially, the primary focus is on stabilizing the patient and alleviating myocardial ischemia. For this patient presenting with NSTEMI, the cornerstone medications include antiplatelet agents, anticoagulants, anti-anginal medications, and medications to address comorbid conditions. Aspirin (81-325 mg daily) is fundamental for inhibiting platelet aggregation and reducing the risk of subsequent thrombotic events (Amsterdam et al., 2019). In addition, a P2Y12 inhibitor such as clopidogrel, ticagrelor, or prasugrel should be administered, especially if percutaneous coronary intervention (PCI) is planned, to further inhibit platelet aggregation (O'Gara et al., 2021).

Nitroglycerin, administered sublingually, can provide rapid relief of chest pain by vasodilation, reducing myocardial oxygen demand. Given the presence of ongoing ischemia, intravenous nitroglycerin may be administered if pain persists (Amsterdam et al., 2019). High-intensity statin therapy, such as atorvastatin or rosuvastatin, should be started early to stabilize atherosclerotic plaques and improve endothelial function. Furthermore, beta-blockers like metoprolol, unless contraindicated, can reduce myocardial oxygen demand, control heart rate, and decrease arrhythmias (O'Gara et al., 2021). Considering his hypertensive state, beta-blockers should be particularly used to lower heart rate and blood pressure, improving myocardial oxygen balance.

In this patient with hypokalemia, correcting potassium levels is essential, especially before administering certain anti-anginal medications, as hypokalemia can predispose to arrhythmias. Additionally, oxygen therapy may be administered if hypoxia develops, along with analgesics for symptomatic relief, and careful monitoring of cardiac rhythm is imperative through telemetry.

2. Medications to be continued after discharge

Post-discharge, the patient should continue a comprehensive medication regimen aimed at secondary prevention of atherosclerotic cardiovascular disease. This includes prolonged dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor, typically for at least 12 months after an acute coronary syndrome (O'Gara et al., 2021). The continuation of statins at high intensity is recommended to promote plaque stabilization and reduce future cardiovascular events. ACE inhibitors or angiotensin receptor blockers (ARBs), such as lisinopril, should be prescribed, especially given the patient’s hypertension and evidence of myocardial injury, as they improve mortality and ventricular remodeling (Gheorghiade et al., 2019).

Beta-blockers should be continued, especially if there are indications such as left ventricular dysfunction, hypertension, or arrhythmias. Calcium channel blockers are generally reserved for patients with contraindications to beta-blockers but may be used selectively. Additionally, addressing his hyperuricemia with urate-lowering therapy and managing comorbidities like diabetes mellitus with appropriate medications, including glycemic control agents, is essential (Gheorghiade et al., 2019). Lifestyle modifications, including smoking cessation, dietary adjustment, weight management, and physical activity, are vital components of secondary prevention.

3. Lifestyle modifications for chest pain management

Addressing lifestyle factors that contribute to cardiovascular risk is pivotal for long-term management. Smoking cessation must be emphasized, given its direct association with coronary artery disease and adverse cardiovascular outcomes. Pharmacological aids such as nicotine replacement therapy or bupropion can be considered to support smoking cessation efforts (Fiore et al., 2018). Weight management through a calorie-controlled, heart-healthy diet, rich in fruits, vegetables, whole grains, lean proteins, and low in saturated fats and trans fats, is vital to reduce obesity-related risk factors (American Heart Association, 2020).

Regular physical activity, tailored to the patient's capacity, should be encouraged, aiming for at least 150 minutes of moderate-intensity exercise per week. Alcohol consumption should be moderated—ideally limited to no more than two drinks per day—to reduce caloric intake, blood pressure, and arrhythmic potential. Furthermore, strict control of hypertension and hyperlipidemia through both lifestyle and medication adherence is essential. Blood glucose levels must be managed effectively within target ranges to mitigate diabetic cardiovascular risks. Stress management techniques like relaxation therapy or meditation may also help reduce overall cardiovascular burden (Kannel & McGee, 2019).

Rationale for Each Question

The initial pharmacological intervention, including antiplatelet agents, nitrates, statins, and beta-blockers, targets immediate stabilization of myocardial ischemia and prevention of thrombotic progression based on current guidelines (Amsterdam et al., 2019). Continuing these medications is critical for secondary prevention because they address ongoing atherosclerosis and reduce recurrence risk (O'Gara et al., 2021). Lifestyle modifications are fundamental to prevent future events by eliminating modifiable risk factors such as smoking, obesity, sedentary behavior, and poor diet. These measures have been shown to significantly decrease the incidence of recurrent coronary events and improve overall cardiovascular health (Kannel & McGee, 2019).
