Jonathan Thomas is a 58-year-old accountant who is being evaluated at the cardiology clinic for angina. He is 5 feet 9 inches tall and weighs 220 pounds, with a waist measurement of 40 inches. He has a history of hypertension, for which he has been prescribed a thiazide diuretic. He admits that he has not been taking the medication lately. His blood pressure on this visit is $154 / 96 \mathrm{~mm} \mathrm{Hg}$. He smokes one pack of cigarettes per day. His LDL cholesterol level is $187 \mathrm{mg} / \mathrm{dL}$. He has no history of diabetes, and his fasting glucose level is within normal limits. He states that he "works out at the gym" 3 days per week. He admits to episodes of midsternal chest pain accompanied by dyspnea and diaphoresis and associated with activity that is usually relieved with rest. He states that these episodes have been increasing in frequency to once or twice weekly. - The nurse is teaching Mr. Thomas about nonpharmacologic management of his angina. What measures can he take to reduce his risk? - Mr. Thomas receives a prescription for sublingual nitroglycerin tablets to use as needed for chest pain and isosorbide mononitrate (Imdur) to take daily. He asks why he needs two prescriptions. How should the nurse respond? - Mr. Thomas continues to experience episodes of angina despite treatment with the nitrate. He receives a prescription for ranolazine (Ranexa). He asks whether he can stop taking the nitrate now. How should the nurse answer this question?

Key Concepts

Acute versus Prophylactic Antianginal Medications

Understanding the difference between acute and prophylactic antianginal therapies is key in managing angina. Acute medications, such as sublingual nitroglycerin, provide rapid relief during an angina attack by quickly dilating coronary vessels to increase blood flow to the heart. Prophylactic medications, like long-acting nitrates (e.g., isosorbide mononitrate), are taken daily to help prevent the onset of angina by maintaining a steady vasodilatory effect and reducing overall myocardial oxygen demand.

Combination Antianginal Pharmacotherapy

Combination pharmacotherapy involves using more than one medication with different mechanisms of action to achieve optimal control of angina symptoms. For example, a patient might be prescribed both a short-acting nitrate for immediate relief and a long-acting agent for prevention, with the addition of other agents like ranolazine for further symptom control when traditional therapies are insufficient. Such a strategy helps in addressing various aspects of the underlying pathophysiology without relying on a single drug, thereby improving overall efficacy.

Lifestyle Modifications in Cardiovascular Disease

Lifestyle modifications are nonpharmacologic measures aimed at reducing cardiovascular risk factors and improving heart health. These interventions include weight loss, dietary changes, regular physical activity, smoking cessation, and stress management. They are crucial because they help lower blood pressure, improve lipid profiles, and reduce overall myocardial oxygen demand, which can lead to a decrease in the frequency and severity of angina episodes.

Patient Education and Medication Adherence

Effective patient education is essential in ensuring adherence to both lifestyle modifications and prescribed medications. Clear communication about the purpose of each medication, differences between acute and prophylactic treatments, and the importance of maintaining a consistent regimen is critical. Patients need to understand why multiple medications may be necessary and that new additions to their regimen do not typically replace existing therapies, but rather work synergistically to manage their condition more effectively.
