Thrombolytic therapy , has been the specific treatment for STEMI for many decades. Primary PCI* is shown to be superior than thrombolysis if performed early by an experienced team in a dedicated facility. (*Conditions apply). It is estimated , currently only a a fraction STEMI population get primary PCI (<5%) in ideal [...]

Apart from acute coronary syndrome, cardiac failure is the most common clinical presentation of CAD. Cardiac failure , classically present with dyspnea on rest or on exertion , while angina is the dominant presentation in ACS.
What if , both these occur together in an acute fashion ?
Yes , if it occurs together [...]

Failed thrombolysis is an important clinical issue in STEMI as successful thrombolysis occurs only in about 50-60% of pateints . The typical criteria to define failed thrombolysis is the regression of less than 50% of sum total( or maximum) ST elevation in infarct leads.
So what do you do for these patients with failed thrombolysis [...]

NSTEMI constitutes a very heterogeneous population .The cardiac risk can vary between very low to very high . In contrast , STEMI patients carry a high risk for electro mechanical complication including sudden death .They all need immediate treatment either with thrombolysis or PCI to open up the blood vessel and salvage the [...]
Management of Atrial septal defect : Device closure lagging behind surgical closure !

Atrial septal defect is one among the commonest congenital heart disease .After years of controversy, there is consensus now , all significant ASDs need to be closed , at whatever age it is detected.
This rule does not apply to small ASDs without chamber right atrial and right ventricular dilatation. These defects and PFOs need not [...]

Acute coronary syndrome is the commonest cardiac emergency. STEMI and NSTEMI are the two clinical limbs of ACS. Generally they have distinct clinical, ECG, angiographic features.(Ofcourse, with some degree of overlap) . It is a mystery , both clinical presentations differ so much inspite of the common denominator , namely , an injured plaque with [...]

How good is Troponin T or I to rule out acute coronary syndrome in the emergency room when a patient presents within two to three hours after the onset of symptoms ?
Very useful
Useful
Rarely useful

Ventricular remodeling follows large myocardial infarction .This term denotes to change in size , shape and function of the ventricle due to altered myocyte geometry .It is now believed , this process begins to occur very early following a STEMI.(less than 24hours)
In which MI remodeling is more common ?
Any MI of large size , especially [...]

Scientifically , the indication for coronary revascularisation should be based on following
Patient’s symptom ( more specifically angina , dyspnea is less important !)
Prov0kable ischemia ( A significantly positive stress test )
Signifcant LV dysfunction with documented viable myocardium & residual ischemia
A revascularisation eligible coronary anatomy * TVD/Left main/Proximal LAD etc ( *Either 1, 2 or [...]
