RESUMEN

Return of blood flow after periodic ischemia is often accompanied by myocardial injury, commonly known as lethal reperfusion injury (RI). Experimental studies have shown that 50% of muscle die of ischemia and another 50% die because of reperfusion. It is characterized by myocardial, vascular, or electrophysiological dysfunction that is induced by the restoration of blood flow to previously ischemic tissue. This phenomenon reduces the efficiency of the present modalities used to combat the ischemic myocardium. Moreover, despite an improved understanding of the pathophysiology of this process and encouraging preclinical trials of multiple agents, most of the clinical trials to prevent RI have been disappointing and leaves us at ground zero to explore newer approaches.

RESUMEN

A rare case of pleomorphic intimal sarcoma of pulmonary trunk is reported. The patient presented with symptoms of right ventricular out flow tract (RVOT) obstruction. Metastatic deposits were seen in lungs, diaphragm and thyroid. Bronchial mucosal involvement was also seen. The tumour showed multicentric origin and on electron microscopic examination in a particular cell line was seen.

RESUMEN

Predischarge two dimensional echocardiography (2D Echo) was performed in 45 survivors of first transmural myocardial infarction to assess its value in predicting major cardiac complications (MCC) during convalescence. Wall motion score was derived for each patient by analysing endocardial motion in 11 left ventricular segments. In 18 months follow up 11 of 14 patients (78%) who had major cardiac complications had wall motion score of at least 5. Wall motion score of less than 5 was present in 29 of the 31 (94%) of patients in asymptomatic group. Non-invasively obtained wall motion score helps in risk stratification of survivors of AMI. Wall motion score at predischarge 2D Echo or more identifies high risk cases from a relatively asymptomatic group (Killip Class I & II).
