American College of Cardiology/American Heart Association (ACC/AHA) guidelines for treatment of hypertension were last published in 2018. Treatment of hypertensive urgencies and emergencies is not discussed here.

Atrial fibrillation (AF) is the most common arrhythmia in the world. Risk factor modification, anticoagulation, rhythm control, and rate control are the four pillars of its management. American College of Cardiology/American Heart Association (ACC/AHA) guidelines on management of AF were updated recently.

An oral nonopioid analgesic is often sufficient for acute treatment of mild to moderate migraine pain without severe nausea or vomiting. A triptan is the drug of choice for treatment of moderate to severe migraine in most patients without vascular disease. Treatment of pain when it is still mild to moderate in intensity improves headache response and reduces the risk of recurrence.

Among patients with chronic heart failure, those with a left ventricular ejection fraction (LVEF) ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF). Patients with a LVEF ≥50% are considered to have heart failure with preserved ejection fraction (HFpEF). Those with a LVEF of 41-49% are an intermediate group more similar to patients with HFpEF.

The FDA has approved vericiguat (Verquvo – Merck), an oral soluble guanylate cyclase (sGC) stimulator, to reduce the risk of hospitalization for heart failure and cardiovascular (CV) death following a worsening heart failure event (hospitalization for heart failure or treatment with IV diuretics as an outpatient) in patients with symptomatic chronic heart failure and left ventricular ejection fraction (LVEF) <45%. Vericiguat is the second sGC stimulator to be marketed in the US. Riociguat (Adempas), which is FDA-approved for treatment of pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension, was the first.

An oral nonopioid analgesic is often sufficient for acute treatment of mild to moderate migraine headache without severe nausea or vomiting. A triptan is the drug of choice for treatment of moderate to severe migraine headache pain in most patients without vascular disease. Early treatment of pain when it is still mild to moderate in intensity improves headache response and reduces the risk of recurrence.

The FDA has approved eptinezumab-jjmr (Vyepti – Lundbeck), a calcitonin gene-related peptide (CGRP) antagonist administered IV once every 3 months, for migraine prevention in adults. It is the fourth monoclonal antibody to be approved for this indication; erenumab (Aimovig), fremanezumab (Ajovy), and galcanezumab (Emgality), which are all given subcutaneously once monthly (fremanezumab can also be given once every 3 months), were approved earlier.

Drugs available for treatment of chronic hypertension and their dosages, adverse effects, and costs are listed in the tables. Treatment of hypertensive urgencies and emergencies is not discussed here.

Treatment of atrial fibrillation includes anticoagulation, rate control, and rhythm control. US guidelines were recently updated.

Patients with a left ventricular ejection fraction (LVEF) ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF). Patients with a LVEF ≤50% and symptoms of heart failure are considered to have heart failure with preserved ejection fraction (HFpEF). There is little evidence that drug treatment improves clinical outcomes in patients with HFpEF.

in the US and their dosages, adverse effects, and costs are listed in the tables. Treatment of hypertensive urgencies and emergencies is not discussed here.

The FDA has approved Byvalson (Allergan), a fixed-dose combination of the beta blocker nebivolol (Bystolic) and the angiotensin receptor blocker (ARB) valsartan (Diovan, and generics), for treatment of hypertension. It is the only combination product that contains nebivolol, and the first to combine a beta blocker with an ARB.

The FDA has approved Entresto (Novartis), an oral fixed-dose combination of the neprilysin inhibitor sacubitril and the angiotensin receptor blocker (ARB) valsartan, to reduce the risk of cardiovascular death and heart failure hospitalization in patients with heart failure with reduced ejection fraction. Sacubitril is the first neprilysin inhibitor to become available in the US.

Heart failure is usually associated with left ventricular dysfunction. According to recent guidelines, patients with a left ventricular ejection fraction (LVEF) ≤40% are considered to have heart failure with reduced ejection fraction (HFrEF) or systolic heart failure. Patients with a LVEF ≥50% and symptoms of heart failure are considered to have heart failure with preserved ejection fraction (HFpEF) or diastolic heart failure; there is little evidence that drug treatment improves clinical outcomes in these patients. The treatment of acute heart failure is not included here.

The treatment of atrial fibrillation includes anticoagulation, rate control, and rhythm control. New US guidelines for the management of atrial fibrillation have recently been published.

Most recent guidelines recommend a BP goal of 140/90 mm Hg. For patients ≥60 years old without diabetes or chronic kidney disease, one guideline recommends 150/90 mm Hg both as the drug treatment initiation threshold and treatment target; this higher target is controversial, except in patients ≥80 years old.

Chronic systolic heart failure is usually associated with a left ventricular ejection fraction (LVEF) of ≤40%. Many patients with symptoms of heart failure have higher ejection fractions, but there is no evidence that drug treatment of heart failure with preserved systolic function (LVEF >40%) improves clinical outcomes. Some of the drugs commonly used now for treatment of chronic heart failure are listed in the table on page 71.

Three retrospective studies have recently reported an association between beta-blocker use and a reduction in breast cancer metastasis and recurrence. No prospective, randomized trials have been published.

They were reviewed in Treatment Guidelines (volume 1, page 19, December 2002) and in The Medical Letter (volume 50, page 73, September 22, 2008).

Nebivolol (Bystolic - Forest) is a new beta-blocker that has been approved by the FDA for treatment of hypertension. It has been marketed in Europe since 1999 for treatment of hypertension and heart failure.

The choice of drugs for treatment of chronic heart failure continues to evolve. Those most commonly used now are listed in the table on page 3. The use of implanted cardiac defibrillators (ICDs) to reduce the incidence of sudden death in patients with heart failure and the treatment of decompensated heart failure were discussed in previous issues.

Drugs available in the US for treatment of chronic hypertension, with their dosages, adverse effects and costs, are listed in the tables that begin on page 40. Combination products are listed on page 47. Drugs for treatment of hypertensive emergencies are not discussed here.

The choice of drugs for treatment of chronic heart failure continues to evolve. It has become increasingly recognized that drugs used in heart failure produce beneficial effects through neurohormonal as well as hemodynamic mechanisms. The treatment of decompensated heart failure is not discussed here; drugs used for this indication were reviewed in Cardiovascular Drugs in the ICU, Treatment Guidelines from The Medical Letter 2002; 1:19.

Drugs available in the US for treatment of chronic hypertension, with their dosages, adverse effects and costs, are listed in the table that begins on page 35. Combination products are listed on page 39. Drugs for treatment of hypertensive emergencies were discussed in Treatment Guidelines volume 1, issue 4, page 19, December 2002.

Some classes of drugs include so many agents that hospital formulary committees, managed care organizations and individual practitioners may find it difficult to choose among them. Fifteen beta-adrenergic receptor antagonists (beta-blockers) are now marketed for systemic use in the USA. One or more have been approved by the FDA for use in hypertension and eight other indications.

Standard treatment for patients with heart failure has included a diuretic, digitalis and an ACE inhibitor. In recent years carvedilol, a nonselective beta-blocker with alpha-1 blocking activity, and the beta-selective blockers bisoprolol and metroprolol have also been used for this indication.

Drugs available in the USA for treatment of chronic hypertension, their dosages and adverse affects are listed in the table and discussed in the text.

The choice of drugs for treatment of heart failure depends on both hemodynamic and neurohormonal factors.

Carvedilol (Coreg - SmithKline Beecham and Boehringer-Mannheim), a betaadrenergic and alpha-adrenergic blocker approved by the FDA for treatment of hypertension in 1995, but not marketed at that time, has now been approved and marketed for treatment of mild or moderate (NYHA class II or III) heart failure stabilized on other drugs. It is being promoted as an add-on drug that reduces the morbidity and mortality of the disease.

Cardiologist now emphasize the importance of neurohormonal as well as hemodynamic factors in the pathophysiology of chronic heart failure (JN Cohn, N Engl J Med, 335:490, August 15, 1996). Drugs that act on different mechanisms are commonly used together.
