Myocardial infarction causes almost 7.3 million deaths each year worldwide. However, current treatments are more palliative than curative. Presently, cell and protein therapies are considered the most promising alternative treatments. Clinical trials performed until now have demonstrated that these therapies are limited by protein short half-life and by low transplanted cell survival rate, prompting the development of novel cell and protein delivery systems able to overcome such limitations. In this review we discuss the advances made in the last 10years in the emerging field of cardiac repair using biomaterial-based delivery systems with focus on the progress made on preclinical in vivo studies...

INTRODUCTION: The subclavian steal syndrome is characterized by the vertebral artery flow inversion, due to a stenotic lesion in the origin of the subclavian artery. The Coronary-subclavian Steal Syndrome is a variation of the Subclavian Steal Syndrome and is characterized by inversion of flow in the Internal Thracic artery that has been used as conduct in a myocardial revascularization. Its diagnosis must be suspected in patients with difference in pulse and arterial pressure in the upper limbs, that present with angina pectoris and that have done a myocardial revascularization...

Hydrogen sulfide is enzymaticaly synthesized by three enzymes - cystathionine gama-lyase (CSE), cystathionine beta-lyase (CBS) and 3-mercaptopyruvate sulfurtransferase (3-MST). After physical training of rats (4 weeks swimming course) we observed in myocardium the increased of these enzymes expression (in 1,5; 2,5 and 5 times accordingly), which accompanied with increased H2S content in myocardium (31,65±1.29 vs 12,6±0,31 nmol/mg protein in control), in miocardial mitochondria (10,55±1,2 vs 4,2±1,1 nmol/mg protein in control) and in plasma (3,75±0,22 vs 2,48±0,08 nmol/mg protein in control)...

The modern cardiology pays much attention to research of myocardial ischemia, especially painless myocardial ischemia as the problem of sudden coronary death. Findings from the current study suggest that antianginal therapy which includes antiaggregant and anticoagulant is effective because of decreasing general myocardial ischemia and its painless form.

The article presents data of the research aimed at the study of obesity in elderly women and interrelations of obesity, its type and severity with changes in the structure and function of the myocardium. The results showed that more than half of elderly women had obesity, mostly mild with a redistribution of adipose tissue in the region of the anterior abdominal wall. Significant left ventricular remodeling and diastolic dysfunction often develop in the patients with obesity than in non-obese ones and depend on the obesity severity and type...

The development of troponins dramatically changed the diagnosis of cardiac injury. Cardiac troponins are the most sensitive and specific biochemical markers of myocardial damage. In 2000. it was elaborated the new definition of miocardial infarction that reflected the importance of that biomarker. The rationale of including troponin assay in the diagnosis pathway was based on the assumption that myocardial necrosis, regardless of its magnitude, should be characterized as myocardial infarction. However, if the patient's clinical picture do no match an elevated troponin result we shoud suspect a false positive value caused by analytical interferences...

UNLABELLED: Chronic myocardial infarction represents one of the most important problems of actual clinical medicine because their incidence is growing especially at young adults (< 45 years) and their mortality with no treatment is high in first month after acute myocardial infarction (50%). When cardiovascular disease is associated with diabetes mellitus, evolution of patients is more serious. AIM: To compare the disease evolution for two groups of patients--one with patients who have purely chronic myocardial infarction and other with patients who have chronic myocardial infarction associated with glycoregulation disturbances (diabetes mellitus, impaired glucose tolerance or impaired fasting glucose)...

Several studies and recent patents have demonstrated that hyperhomocysteinemia (HHCY) is an independent risk factor for congestive heart failure (CHF); it is also correlated to the severity of the disease. In literature there are some data about effects of HHCY on myocardial structure and function in animal models. These studies indicate a direct effect of HCY in promoting reactive myocardial fibrosis and systolic dysfunction, promoting miocardial redox state, endothelial and mithocondryal dysfunction, negative inotropic effect...

Sudden cardiac death (SCD) - this natural death caused by cardiac reasons and which is characterized by sudden loss of consciousness within first hour after revealing of sharp clinical symptoms. A primary factor of SCD is not traumatic. It occurs suddenly and unexpectedly. The high risk of development of sudden cardiac death is basically associated with ventricular arrhythmias. Electrophysiological anomalies in cells lead to development of ventricular ectopic activity or ventricular tachycardia which comes to the end with fibrillation...

Gallstone ileus is a rare complication of gallstone disease, accounting for 1-4% of all bowel obstructions. The phisiopathology is related to the presence of a bilio-enteric fistula. Cholecistoenteric fistulae occur in fewer than 1% of patients with gallstone. We present the case of an 83-years-old woman, complaining of acute abdominal pain, vomiting and mechanical obstruction at admission. She reported a past history of hypertension, recent miocardial ischaemia, diverticular disease and cholelithiasis. A CT scan revealed aerobilia, gastric and duodenal dilatation and a gallstone impacted just beyond the duodeno-jejunal junction...

A serendipitous discovery by William Smith Tillett in 1933, followed by many years of work with his student Sol Sherry, laid a sound foundation for the use of streptokinase as a thrombolytic agent in the treatment of acute myocardial infarction. The drug found initial clinical application in combating fibrinous pleural exudates, hemothorax, and tuberculous meningitis. In 1958, Sherry and others started using streptokinase in patients with acute myocardial infarction and changed the focus of treatment from palliation to "cure...

Cardiogenic shock (CHC) associated to acute myocardial infarct has high mortality and their manifestations are heterogenous. In our institution historical mortality, was 98%, but with different methods of reperfusion, its reduced to 53%. In other hand, with opportune clinical stratification is useful to improve the treatment strategy. This stratification on basis in clinical signs: age, infarction location, cardiac frequency and systemic arterial pressure, and hemodynamical valuation with the use of right catheterism with quantification miocardial work parameters like "Cardiac power" that is the product of flow and arterial pressure and that is of utility to know the "Miocardial reserve"...
