What is the infarct size?

What is the infarct size?

Infarct size is directly associated with mortality; patients with an infarct >12% of the left ventricle (LV) have a 7% mortality at 2 years as compared to 0% with an infarct <12% of the LV. Therefore, it is important to optimise the strategy to minimise infarct size.

Can an infarct heal?

The presence of mononuclear cells and fibroblasts and the absence of polymorphonuclear leukocytes characterize a healing infarction. A healed infarction is man- ifested as scar tissue without cellular infiltra- tion. The entire process leading to a healed infarction usually requires five to six weeks or more.

What is an infarct extension?

Infarct extension is defined clinically as early in-hospital reinfarction after a myocardial infarction. The pathologic finding of infarct extension is necrotic and healing myocardium of several different recent ages within the same vascular territory.

What is the infarct?

External Websites. Infarction, death of tissue resulting from a failure of blood supply, commonly due to obstruction of a blood vessel by a blood clot or narrowing of the blood-vessel channel. The dead tissue is called an infarct.

How does myocardial infarct heal?

When a heart attack occurs, the heart muscle that has lost blood supply begins to suffer injury. The amount of damage to the heart muscle depends on the size of the area supplied by the blocked artery and the time between injury and treatment. Heart muscle damaged by a heart attack heals by forming scar tissue.

How long does it take to recover from myocardial infarction?

Most patients stay in the hospital for about a week or less. Upon returning home, you will need rest and relaxation. A return to all of your normal activities, including work, may take a few weeks to 2 or 3 months, depending on your condition. A full recovery is defined as a return to normal activities.

What causes infarct expansion?

Infarct expansion, defined as an alteration in the ventricular topography due to thinning and lengthening of the infarcted segment, develops within the first few hours of the acute symptoms, mostly in patients with a large, transmural, anterior myocardial infarction.

Which of the following is a complication of myocardial infarction?

Mechanical complications of acute myocardial infarction (AMI) are ventricular septal defect (VSD), papillary muscle rupture or dysfunction, cardiac free wall rupture, ventricular aneurysm, dynamic left ventricular (LV) outflow tract (OT) obstruction, and right ventricular (RV) failure.

What are the survival rates for ovarian cancer?

Below is the relative five-year survival rate for epithelial ovarian cancer: Stage Survival Rate 3A 59% 3B 52% 3C 39% 4 17%

How is infarct size predicts the prognosis?

Infarct volume was found to significantly predict outcome. Mean infarct volume in the independent patients was 35.7±29.7 cm 3 compared with 88.3±71.3 cm 3 in dependent patients and 166.5±65.9 cm 3 in dead patients (F=10.52, P <.001).

What happens if you have an infarcted ovarian cyst?

In case of infarcted ovarian cyst, these cysts suffer from obstructed blood supply and limited supply of oxygen, ultimately leading to the death of the cyst or infarction. This usually happens when the uterus undergoes ovarian torsion.

Is the risk of stroke higher in ovarian cancer patients?

After a median follow-up of 2.68 and 3.85 years, respectively, the ischemic stroke incidence was 1.38-fold higher in the ovarian cancer cohort than in the comparison cohort (9.4 versus 6.8 per 1,000 person-years), with an age- and comorbidity-adjusted HR of 1.49 ( P <0.001).
