Cardio-vascular diseases are the leading cause of morbidity and mortality. Ischemia is a state of oxygen deprivation in tissues, whereas reperfusion is restoration of blood flow in ischemic tissues. Myocardial damage of tissue during reperfusion after ischemic insult is known as myocardial ischemia-reperfusion (I/R) injury. It induces damage to cardiac muscle via increasing expression of oxygen, sodium and calcium ions which are responsible in the activation of proteases and cell death. Heart renin angiotensin system (RAS) plays an important role in the myocardial ischemia and reperfusion injury. Angiotensin (1-7) is responsible for vasodilation and angiotensin II for vasoconstriction. Here-in we reviewed how myocardial I/R injury sets in by up-regulation of angiotensin II that leads to increased infarct size, which can be reduced by the use of ACE inhibitors, ACE2 activators and angiotensin II antagonist.

Xuesaitong injection (XST), which mainly consists of Panax notoginseng saponins, has been widely used for treating cardio-cerebral vascular diseases. However, the underlying mechanisms of XST associated with its cardioprotective effects are still unclear. To identify the potential target proteins of XST, two-dimensional gel electrophoresis (2-DE)-based proteomics was utilized to analyze the protein profile of myocardium in rats with myocardial ischemia/reperfusion (I/R) injury. The differentially expressed proteins were identified by matrix assisted laser desorption/ionization time-of-flight mass spectrometry. It is interesting that XST can alter the expression of 7 proteins, including pyruvate dehydrogenase E1 alpha (PDHA1), hydroxyacyl-coenzyme A dehydrogenase (HADHA), peroxiredoxin 3 (PRX3), gamma-enolase, acetyl-coenzyme A acyltransferase 2 (ACAA2), etc. Functional analysis revealed that those proteins were chiefly related to cardiac energy metabolism and oxidative stress. The cardioprotective effects of XST were further validated in H9c2 cardiac muscle cells with hypoxia/reoxygenation injury. We found that XST can promote the activity of PDH, an important enzyme related to the TCA cycle, as well as increase the intracellular content of acetyl-CoA and ATP. Moreover, XST also attenuated intracellular MDA release in H2O2-injured cardiac cells. This is the first study on the proteomic expression of XST-treated myocardium with I/R injury to reveal that the cardioprotective effects of XST may be attributed to the PDH-mediated restoration of aerobic glucose oxidation.

Muscular dystrophy (MD) connotes a heterogeneous group of inherited disordersaffecting skeletal and cardiac muscle. Inseveral forms of MD, the cardiac disease may be the predominant manifestationof the underlying genetic myopathy. The cardiacinvolvement is due to progressive interstitial fibrosis and fatty replacement inboth the atria and ventricles, which may lead to cardiomyopathy, conductiondefects and tachyarrhythmias. Angiotensin-convertingenzyme inhibitors (ACE-Is) modulate the production of angiotensin II and limitthe amount of fibrosis in the myocardium, reducing mortality andhospitalization in cardiac patients. The aim of present review is to describethe antifibrotic proprieties of ACE inhibitor therapy and to summarize thecurrent body of scientific literature relating to the use of ACE-Is for theprevention and treatment of cardiomyopathy in patients with musculardystrophies.
