How common is myocardial wall motion defects in the absence of ischemia or infarction ? by Dr. Sangareddi V. Medical Doctor Posted Mon 14 Dec 2009 6:30am Myocardial wall motion defects are sine qua non of  coronary artery disease. This occurs as regional wall motion defects following myocardial infarction or during unstable angina.Myocardium is divided into 16 segments  for this purpose. The wall motion defect occurs in the respective segments , depending upon the compromised  coronary arteria ... Read on »
A partial list of chest pain in the “Post-Infarction” period by Dr. Sangareddi V. Medical Doctor Posted Mon 21 May 2012 11:07pm We know prompt reperfusion of infarct related artery( IRA) by any means  constitute the specific management of  STEMI .However, It needs  to be emphasized ,  treatment process of STEMI  is not over after  primary  PCI or thrombolysis .Early hours after a PCI or thrombolysis  is vital as well .The ill-fated coronary arteries are as  vulnerable a ...

How can an embolism cause a hemorrhagic infarct? by pathologystudent Posted Mon 24 Feb 2014 12:58pm Q. I am confused as to how an embolism can cause a haemorrhagic infarct. To me, emboli are little chunks of clot that float around and get stuck in vessels. Shouldn’t this cause an ischemic infarct? Also, a hemorrhagic infarct is named for its color (not for its underlying mechanism), right? But then how do you get a hemorrhagic infarct ... Read on »
Article review: EKG interpretation by the computer by Michelle Lin Medical Doctor Posted Mon 25 Jan 2010 12:00am What is your reading of this EKG? Having a computer interpretation printed on EKGs is always a nice backup when reading EKGs. In my experience, the reading is a useful adjunct but it sometimes "overcalls" ST elevation MIs. It is great, though, in picking up subtle pacemaker spikes and calculating QTc intervals. In this publicatio ... Read on »
Pathological condition â?? Acute Myocardial Infarction by Ayurvedic Physician- Dr. Maulik BV Posted Fri 26 Jun 2009 10:58pm Acute Myocardial Infarction (MI) can be defined as condition in which, there is death or necrosis of myocardial cells. It is generally diagnosed at the end of the ambit of myocardial ischemia or acute coronary condition. Myocardial infarction occurs once myocardial ischemia oversteps a critical threshold and overcomes myocardial cellular repairin ... Read on »
What are the causes of ST segment depression in V1 , V 2, and V3 in inferior myocardial infarction ? by Dr. Sangareddi V. Medical Doctor Posted Tue 20 Sep 2011 1:00pm ST segment depression is a fairly common observation in anterior precardial leads. It   is  due to  Pure electrical phenomenon (Referred to as reciprocal changes)*  Additional  ischemia in LAD territory  It could imply  the IRA  is  a critically occluded  LCX and STEMI is actually an   infero -posterior STEMI  Simply  indicat ...

What’s the difference between ischemic and hemorrhagic brain infarcts? by pathologystudent Posted Mon 02 Jan 2012 10:53am   Q. I’m studying for boards and came across a point of confusion. What is the difference between a hemorrhagic and ischemic infarct? I thought that one was due to a thrombus (a stationary clot) and the other was due to an embolus (a clot that forms then moves to another part of the body then gets stuck). But Robbins says that the thr ... Read on »
SIRT2 Inhibitors as Novel Therapeutics for Myocardial Infarction and Ischemic Stroke and to Prevent Necrosis by Posted Tue 22 Jan 2013 7:00pm Description of Invention: Sirtuin 2 (SIRT2) inhibitors to reduce necrosis and, thereby, as novel therapeutics to treat ischemic stroke and myocardial infarction. Accumulating evidence indicates that programmed necrosis plays a critical role in cell death during ischemia-reperfusion. NIH investigators have shown that the NAD- ... Read on »
What is Myocardial Infarction? by JaniferDoctorMedson Posted Wed 19 Sep 2012 5:35am The heart is the organ of the body that works harder. Throughout life, is responsible for pumping blood continuously filled with oxygen and vital nutrients through a network of blood to all organs and tissues of the body. It has its own blood, known as coronary arteries, which carry oxygen-rich blood to the heart muscle ( myocardium ). ... Read on »
