Why is it important to estimate future risk of cardiovascular disease and clinical ASCVD for patients without certain medical histories?

To guide treatment decisions even without specific medical histories

Which factor determines the choice of initial antihypertensive drug therapy?

Compelling indications

What is recommended for patients with stage 1 hypertension?

First-line antihypertensive drug

When is combination drug therapy recommended?

For patients with more severe BP elevation (stage 2 HTN)

Which class of antihypertensive agents are preferred as first-line agents for most patients?

ACEIs, ARBs, CCBs, or thiazides

When should beta-blocker therapy be reserved according to the text?

To treat compelling indications only

Which drugs are considered alternative drug classes that may be used in select patients after first-line agents?

Which type of calcium channel blockers (CCBs) do not alter conduction through the AV node and are not effective agents in supraventricular tachyarrhythmias?


Which side effect is unique to verapamil compared to diltiazem?


Which calcium channel blocker (CCB) is associated with negative inotropic effects but to a lesser extent than verapamil?


What is the main reason behind cardiac conduction abnormalities associated with diltiazem and verapamil?

Preexisting cardiac conduction abnormalities

What effect may dihydropyridines cause due to their potent peripheral vasodilating effects?


Which cytochrome P450 isoenzyme system do verapamil and diltiazem inhibit?


Why are immediate-release nifedipine not approved for the treatment of hypertension?

Peripheral edema and dizziness

Which type of CCBs are very effective in older patients with isolated systolic hypertension?

Dihydropyridine CCBs

Why should verapamil and diltiazem be given cautiously with a β-blocker?

Increased risk of heart block

$5(7 + 3)$ quantities or more daily

Test your knowledge on the side effects of nondihydropyridine calcium channel blockers such as diltiazem and verapamil. Learn about the risk of cardiac conduction abnormalities, negative inotropic effects leading to heart failure, gastrointestinal issues like constipation, and other common adverse reactions.
