Keypoints about the use of Beta Blockers


Major points about the use of betablockers 

1-All betablockers can cause reduction in HDL level except CARVEDILOL


2-All betablockers can cause hypertriglyceridaemia except CARVEDILOL


3-The betablocker of the choice in renal patients on dialysis+HF is CARVEDILOL


4-Target dose of CARVEDILOL is patients with HFrEF is 25mg twice (50mg twice if body weight 85Kg or more )


5-The best antihypertensive effect among betablockers is observed with CARVEDILOL and nebivilol


6-The best rate controlling effect among betablockers is observed with bisoprolol and metoprolol


7-The most selective beta1 blocker is nebivilol, so it the most suitable for patients with asthma or COPD


8-The lowest incidence of erectile dysfunction among betablockers is observed with Nebivilol, it improves ED due to its vasodilating properties.


9-Betablocker can control HR in AF during rest and exercise(while digoxin control HR at rest only)


10-Betablockers are considered the fifth antihypertensive drug (after ACEI, ARBs, CCB, thiazide diuretics) except in pregnancy, Arrhythmias(AF), angina or HF ; in these cases, Betablocker can be used as first line for hypertension.


11- Metoprolol tartarate has short half life so should be given twice daily, whereas succinate has long half life which pwrmits once daily dosing

STEMI ECG Criteria and Universal Definition of MI

  STEMI ECG Criteria and the Universal Definition of Myocardial Infarction: A Complete Guide for Clinicians Early and accurate diagnosis of acute myocardial infarction (AMI) remains the cornerstone of reducing morbidity and mortality in patients presenting with chest pain. Among all forms of acute coronary syndromes (ACS), ST-elevation myocardial infarction (STEMI) represents the most time-sensitive emergency, requiring immediate reperfusion therapy. This article provides a clinically relevant summary of the STEMI ECG criteria and the Universal Definition of Myocardial Infarction (UDMI), based on the latest consensus guidelines from the ESC, ACC, AHA, and WHF. --- 1. Understanding STEMI: Why Accurate ECG Interpretation Matters A 12-lead ECG remains the first and most critical diagnostic test when evaluating suspected myocardial infarction. STEMI is identified when there is evidence of acute coronary artery occlusion, producing transmural ischemia and characteristic ST-segment eleva...

Learn Echocardiography | Standard Protocol for Performing Comprehensive Echocardiogram | Explained with Images and Videos

  If you are just starting to learn echocardiography, you will find that learning the full echo examination protocol will be immensely useful. The full protocol will provide a solid foundation for your career in echo. I personally found that once I could execute the standard protocol flawlessly, I was able to add and refine additional echo scanning skills while deepening my understanding of the purpose of each echo image. The echo protocol illustrated in this article is the same one we currently use for all our patients in the hospital and meets or exceeds the standards of American Society of Echocardiography (ASE) for an adult echocardiography examination. The protocol presented here is meant as a guideline and does not cover every aspect (such as off axis views) of an echo examination. Also other hospitals will probably have slight variations of this protocol depending on the lab's needs, which is normal. This article's main purpose is to provide a solid foundation for ...
