Now It's the Cardiologists' Turn
People like to rag on psychiatry: we've got our own anti-psychiatry movement, and one of the biggest issues for these groups is that "psychiatry" (whoever our singular voice might be) misrepresented itself by saying there are chemical imbalances responsible for mental illness, when no precise imbalance has yet been identified.  We're not like internal medicine and it's sub-specialties where there are numbers and a cut-off for when you have diabetes, and when your cholesterol raises your risk of heart disease.  Those numbers are reportedly precise science, but, actually, those illnesses are defined like psychiatri...

Is RF ablation possible in Rheumatic Atrial fibrillation ? ?
No procedure is  impossible in medicine    . . . but it should be useful for the patient ! Where will you ablate ? What is the purpose ? The much  hyped*  ablation of pulmonary vein  is never going to help in rheumatic heart since  arrhythmia focus occurs at  random . How can you  locate a   focus of AF over a  huge , scarred  left atrium  ? ( which looks like a lunar surface  sprinkled with a rocky terrain ! )                                       Note the huge , scarred LA .It would                                       be a w...

Two interrupted sinus beats. What is the etiology?
In this study of 35 patients with sick sinus syndrome, as diagnosed by (1) age at least 45 years; (2) mean sinus rate at rest less than 45 beats/min, and/or intermittent sinoatrial block in at least 1 standard electrocardiogram recorded during diurnal hours on different days; (3) symptoms attributable to sinus node dysfunction, such as syncope or dizziness, and/or easy fatigue or effort dyspnea, the patients were followed up for up to 4 years (mean 17 ± 15 months). During follow-up, 20 patients (57%) had cardiovascular events that required treatment: 8 had syncope (23%); 6 had overt heart failure (17%); 4 patients had chr...

Biomarkers in acute coronary syndrome
Creatine (CK) and Isoenzymes Three CK isoenzymes described are the MM, MB and BB fractions. In 1970’s, MB fraction was shown to be elevated in and highly specific for acute myocardial infarction. Later it was shown that CK-MB can be released from skeletal muscles as well, especially regenerating skeletal muscles. This lead to a search for better more specific markers of acute myocardial necrosis. CK-MB level begins to rise 4-6 hours after myocardial infarction and it takes up to 12 hours for it to be elevated in all patients with myocardial infarction. CK-MB levels return to baseline within 36-48 hours. Hence it is the m...

The George W Bush stent case: An incredible teaching opportunity on the basics of heart disease
The wrist artery hardly had time to seal. (Surely it was a radial.) The controversy came that fast. The drumbeat of naysayers seemed to start only minutes after a prideful press release announced that George W Bush had undergone successful cardiac stent placement. The ever-quotable cardiologist from Cleveland Clinic, Dr. Steven Nissen, said, “This is really American medicine at its worst.” Dr. David L Brown, from Stony Brook University, and author of an important 2012 study on stents, added that GWB was “now the poster child for the inappropriate use of stenting.” How could this be? It must be a good thing to uncov...
