What is the first-line treatment for newly diagnosed hypertension in a patient without comorbid conditions?

The first-line treatment for newly diagnosed hypertension in a patient without comorbid conditions is thiazide diuretics. This recommendation is supported by numerous clinical guidelines, including those from the American College of Cardiology and the American Heart Association. Thiazide diuretics effectively lower blood pressure by promoting the excretion of sodium and water through the kidneys, which helps to reduce blood volume and subsequently decrease arterial pressure.

In patients without compelling indications for another class of antihypertensive (such as heart failure or renal disease), thiazide diuretics have demonstrated efficacy in lowering blood pressure and reducing cardiovascular morbidity and mortality. They are particularly beneficial because they not only control blood pressure but also have a mild diuretic effect that can help with fluid management.

While other classes of medications, such as ACE inhibitors, beta-blockers, and calcium channel blockers, are also used to treat hypertension, they are typically recommended in specific patient populations with particular comorbidities or risk factors. For instance, ACE inhibitors are often preferred in patients with heart failure or diabetes due to their renoprotective properties, while beta-blockers are primarily used in patients with ischemic heart disease or arrhythmias. Calcium channel blockers can be effective but are usually considered
