Superior Mesenteric Artery Embolus as a Delayed Complication of a Cocaine Induced Myocardial Infarction
Cocaine has acute and chronic effects on health as well as addiction and dependence and places a significant burden on healthcare systems. After cannabis, it is the most frequently used illicit drug worldwide. It is estimated that between 14 and 21 million people use the drug each year . Its main adverse effects occur in the cardiovascular system. Cocaine causes sympathomimetic actions such as tachycardia, hypertension and coronary artery constriction due to enhancement of release of catecholamines. It enhances thrombus formation by activating platelets and potentiating thromboxane production . The consequences of these effects include chest pain, myocardial infarction, aortic dissection, coronary artery aneurysm, myocarditis, cardiomyopathies and arrhythmias. Our case demonstrates a young patient who had a delayed presentation of a myocardial infarction, in the setting of recent cocaine use that was complicated by an apical thrombus which resulted in distal emboli to his superior mesenteric artery and left renal artery. It highlights the fact that in a young patient with no other risk factors how complications may arise, even weeks after cocaine use.
Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. Pioglitazone (PIO) is used for the treatment of type 2 diabetes mellitus and there is some evidence that it may improve ventricular function in diabetic patients.
Could Non-Linear Heart Rate Variability Analysis of Short RR Intervals Series Give Clinically Valuable Information in Heart Disease?
New analytic methods based on nonlinear system theory have been developed to characterize the nonlinear features in HR dynamics. It is known from long time series (24h ECG recordings) that patients with chronic heart failure or stable coronary heart disease have altered fractal organization in heartbeat dynamics. During such long-time series, many confounding could limit the assessment of autonomic functions.
Therapeutic Hypothermia Still Effective in Prevention of Anoxic Encephalopathy following Extended Period of Pulselessness during Cardiac Arrest
There are approximately 300,000 out-of-hospital cardiac arrests per year with less than 10% of those surviving. More than half of survivors suffer permanent neurologic deficits. Therapeutic hypothermia has proven effective at thwarting neurologic damage occurring in the 16-hour window following return of spontaneous circulation (ROSC). Despite recommendations by the American Heart Association (AHA), many cardiologists have been slow to implement therapeutic hypothermia. While many trials have discussed the relevance of initial rhythm and delay of cooling, there has been limited discussion of the efficacy of therapeutic hypothermia in the presence of extended pulselessness.
