2. Beta blocker - Wikipedia

   en.wikipedia.org/wiki/Beta_blocker

   Beta blockers are known primarily for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart failure. [17] Beta blockers, in addition to their sympatholytic β 1 activity in the heart, influence the renin–angiotensin system at the kidneys.

   They're prescribed to people with some irregular heart rhythms, heat attacks, heart failure, chest pain and other cardiovascular problems. Churchwell added beta blockers are one of the most ...

   Beta-blockers. Beta-blockers are stopped or decreased in people with acutely decompensated heart failure and a low blood pressure. However, continuation of beta-blockers may be appropriate if the blood pressure is adequate. [16] Inotropic agents. Inotropes are indicated if low blood pressure ( SBP < 90 mmHg ) is present.

   In particular, beta-blockers with intrinsic sympathomimetic activity are contraindicated in patients with myocardial infarction, heart failure or severe bradycardia. [ 15 ] [ 16 ] Beta-blockers should be used with caution in patients with asthma or chronic obstructive pulmonary disease (COPD) due to bronchoconstriction, and in patients with ...

   Some evidence suggests that vasodilating beta blockers, such as nebivolol, can provide a benefit for patients with heart failure regardless of ejection fraction. [58] Additionally, because of the chronotropic perturbation and diminished LV filling seen in HFpEF the bradycardic effect of beta blockers may enable improved filling, reduce ...

   heart failure. The cardio-selective beta-1 blockers could cause adverse effects including bradycardia, reduced exercise ability, hypotension, atrioventricular nodal blockage and heart failure. [5] Other possible adverse effects include nausea and vomiting, abdominal discomfort, dizziness, weakness, headache, fatigue, and dryness in mouth and ...
