CHF treatment options
Why are calcium channel blockers (CCB) contra-indicated in congestive heart failure, while beta-blockers aren't?
I understand that CCB may worsen the situation with a significant drop in cardiac output (CO), since they're negative inotropes and can further deteriorate the cardiac function.... but don't beta-blockers ultimately do the same thing? They're negative chronotropes, so they will also cause a decrease in CO. Why can they be used in heart failure while CCB cannot?
Thanks in advance. (Source: Student Doctor Network)

Which is first: HF or HTN?
How to differentiate between:
1. Hypertension causing hypertrophy and eventual heart failure and congestion
and
2. congestive heart failure for another reason causing decreased renal blood flow and increased RAAS leading to HTN?
I came by a Q in UW (qid: 1532) where they show a patient presenting with CHF and HTN and ask about angiotensin II levels in his pulmonary veins.
The answer was increased, because the patient has scenario number 2.
What if it was scenario...

Light's Criteria Calculator
by shilpamary (Posted Thu Jun 16, 2016 10:44 am)Recently, I have checked in https://www.easycalculation.com/medical ... ulator.php calculator about the calculation of light's criteria based on protein and LDH parameters. Also I have studied about light's criteria in biology in which pleural effusion is a type of fluid, built in the space of lungs and chest cavity. The main causes for Pleural effusion are Congestive heart failure, kidney failure, infection, malignancy, pulmonary embolism, hypoalbuminemia, cirrhosis, trauma and so on.Do we have treatment for this type of exudates and will it get cure completely?

What your patient is thinking: "My experience of stressed out staff..."
Growing up with pioneering treatment is the latest What your patient is thinking piece from The BMJ. It is written by Liza Morton who was the world's first 11 day old baby with congestive heart failure to be attached to an external cardiac pacemaker for complete heart block. She was fitted with five early implantable pacemakers by thoracotomy before age 7, she had surgical repair of her atrial septal defect and her first variable rate pacemaker in her early teens, and four further variable rate pacemakers.
She describes her childhood memories of being treated for congenital h...

Diagnostic and therapeutic dilemma
62 year old Caucasian woman with a history of diabetes on oral hypoglycemics,active smoker; hospitalized in the recent past for congestive heart failure came in with pulseless electrical activity(PEA) arrest.Ejection fraction (EF) on recent echo done 1 week prior was 65% with mildinferolateral wall hypokinesis. She is admitted this time with respiratory failure leading to intubation in the field, followed by PEA arrest on arrival in the emergency. Resuscitated after 4-5 minutes of cardio-pulmonary resuscitation-no purposeful movements noted, but patient opens eyes spontaneously.Electrocardiogram after resuscitation a...

Why is there a young woman advantage? Why is it lost?
The answer to this question has been elusive. The Women’s Health Initiative was supposed to answer these questions but failed to find the advantage. During my stent as cardiology champion, the notion of fundamental laws of biology and a model of health and disease began to form. I used these principles to determine the difference between men and women. The results of this endeavor are now available on line in the article. Houck, PD. Why is there a young woman advantage? Why is it lost? Applying the laws of biology to men and women. JCvD 2014. In press.

ECG in LVH: Quiz 6
This 46 years old woman had been well and without hypertension or knowledge of heart disease until two years before, when she began to develop exertional dyspnoea. Recently, typical congestive heart failure developed. Her blood pressure was found to be 110/70 mm of Hg. Cardiac examination revealed no murmur, but S3 and S4 gallops were present. CXR-PA view showed generalized cardiomegaly and pulmonary congestion. An ECG was recorded and revealed the following- How would you interpret this ECG? (Note that the precordial leads are recorded at half standard)Please click to enlarge the view. (Source: Doc2Doc BMJ Cardiology)
