Include in your answer: (i) (ii) the neural mechanisms that come into play immediately to maintain arterial pressure (short-term). (Suggested time: 10 minutes) the hormonal mechanisms that might be important over the medium-term to maintain arterial pressure and increase blood volume.

Managing and Reducing Cardiovascular Risk In Type 2 Diabetes Mellitus INTRODUCTION Diabetes mellitus is a metabolic disorder in which the body’s capacity to make use of glucose‚ fat and protein is disturbed due to insulin deficiency or insulin resistance. It is a hormone secreted from pancreas that helps glucose from food to enter the body ’s cells where it is transformed into energy required by muscles and tissues to function. Diabetes is caused either because the pancreas does not secrete

Naturally‚ we called a Code heart and went straight up to the cardiac catheter lab. The next thing I knew‚ I was looking at a literal heart of a literal person on a monitor with all the blockages that caused the infarction. After the stents were placed it looked like a completely different healthy heart with no blockages to be seen. Obviously I have

From 2006-2008‚ I worked at Karachi Institute of Heart Diseases as Resident Medical Officer‚ during my training I learned not only mechanism‚ pathogenesis‚ diagnosis‚ differential diagnosis and management of cardiovascular diseases but also gained tremendous knowledge in general Internal Medicine by diagnosing and treating complications of Myocardial Infarction and Post Angiography patients like Respiratory compromise and Renal failure.

accumulation of fluid and reduces blood flow out of the heart. The 3rd heart sounds indicates left ventricular dysfunction and the rapid filling of the ventricle. The temperature of 37.5°c is a systemic manifestation of the inflammatory process caused by myocardial cell death (Bucher et al.‚ 2015). The nursing strategy is to assess the patient’s cardiac and hemodynamic status through monitoring the arterial line‚ ECG‚ and fluid status. Immediate detection of complications is

blockage in the coronary arteries of the heart. Once the blood flow to heart tissue decreases or stops completely‚ the heart tissue is damaged and can lead to further complications including a myocardial infarction. Another form of cell injury is free radicals and reactive oxygen species. “An important mechanism of cellular injury is injury induced by free radicals‚ especially by reactive oxygen species (ROS); this form of injury is called oxidative stress” (Heuther and McCance‚ 2012).

associated with increased deposition of matrix proteins in the myocardium. The expansion of the cardiac interstitial space in absence of significant cardiomyocyte loss is “reactive interstitial fibrosis” and the formation of scar in response to myocardial infarction is called “reparative fibrosis” [10‚ 46]. Increased deposition of endomysial and perimysial collagen leads to interstitial fibrosis in fibrotic heart (Figure 5). Increased collagen deposition in adventitia of intramural coronary arterioles
