Acute effects of cocaine include decreased food intake‚ increased activity‚ effusiveness‚ and diminished fatigue. Repetitive motor activity is observed with higher doses. Overdose can result in convulsions‚ hyperthermia

The most common cardiovascular complications in Marfan syndrome are dilatation of aortic root and mitral valve prolapse‚ whereas in beals syndrome the cardiac finding includes aortic enlargement and/or mitral valve regurgitation.The overlap in clinical features has a molecular basis. Beal’s Syndrome and Marfan Syndrome result from mutations in two homologous genes‚ FBN2 and FBN1‚

to record‚ analyze‚ and confirm heart murmurs. The SensiCardiac provides a full cardiac murmur assessment within two minutes. No special training is required and the “app” handles reading the assessment. It records four 20 seconds readings; in the Aortic‚ Pulmonary‚ Tricuspid and Apex area. And these findings can be converted to a pfd file. The SensiCardiac is optimised for iOS 6 and the iPhone 4S/5‚ to be used in with a Littmann 3200 or ThinkLabs ds32a+ stethoscope. And this technology is HIPPA

The heart pumps blood from the left ventricle into the aorta through the aortic valve. Its small branches supply blood to the ribs and some chest structures.

Surgical intervention may be necessary in patients whose heart failure is due to severe aortic stenosis. They can undergo aortic valve replacement or transcatheter aortic valve implantation (NHS‚ 2016). Extracorporeal membrane oxygenation can be used after surgery to aid the transition from cardiopulmonary bypass to ventilation (NICE‚
