Myocardial edema after ischemia/reperfusion is not stable and follows a bimodal pattern: imaging and histological tissue characterization.

BACKGROUND It is widely accepted that edema occurs early in the ischemic zone and persists in stable form for at least 1 week after myocardial ischemia/reperfusion. However, there are no longitudinal studies covering from very early (minutes) to late (1 week) reperfusion stages confirming this phenomenon. OBJECTIVES This study sought to perform a comprehensive longitudinal imaging and histolo...

Pathophysiology Underlying the Bimodal Edema Phenomenon After Myocardial Ischemia/Reperfusion.

BACKGROUND Post-ischemia/reperfusion (I/R) myocardial edema was recently shown to follow a consistent bimodal pattern: an initial wave of edema appears on reperfusion and dissipates at 24 h, followed by a deferred wave that initiates days after infarction, peaking at 1 week. OBJECTIVES This study examined the pathophysiology underlying this post-I/R bimodal edematous reaction. METHODS Forty...

Building a Unified Mechanistic Insight Into the Bimodal Pattern of Edema in Reperfused Acute Myocardial Infarctions: Observations, Interpretations, and Outlook.

O ver the past 50 years, the understanding of the pathophysiology of myocardial edema in the setting of acute myocardial infarction (MI) has evolved significantly. Controlled animal studies have demonstrated that ischemia or transient ischemia followed by reperfusion lead to myocardial edema. In particular, ischemia promotes intracellular edema and the extent of edema is directly related to isc...

Depression follows Myocardial Infarction

Unfortunately, depression is now a well documented independent risk factor of coronary artery disease. Post-myocardial infarction (MI) patients with a clinician-diagnosed depressive disorder or self-reported depressive symptoms carry a 2.0to 2.5-fold increased relative risk of new cardiovascular events and cardiac mortality Questions about the pathophysiologic mechanism of depression in this se...
