Although right ventricular infarction has been described for many years at autopsy, the hemodynamic impact was not well recognized until the report of Cohn et al in 1974. Since it is essential to recognize early signs of predominant right ventricular infarction because it may require a unique form of therapy, several clinical and electrocardiographic studies have attempted to detect right ventricular involvement in acute myocardial infarction. Necrosis of a large proportion of the right ventricle causes a hemodynamic derangement characterized by systemic hypotension and disproportionate elevation of right ventricular filling pressure compared to left ventricular filling pressure. This in turn causes an elevation of the central venous pressure (jugular venous pressure), one of the hallmarks of the bedside diagnosis of right ventricular infarction. pilocarpine-eyedrops.com (more…)

  • Rapid Hemodynamic Improvement in Right Ventricular Infarction After Coronary AngioplastyRight ventricular infarction is a common association of acute inferior myocardial infarction and usually is not associated with adverse consequences. Isolated right ventricular infarction is rare and has been described as being associated with occlusion of side branches of the right coronary artery2 or with a non-dominant right coronary artery. Acute necrosis of a large part of the right ventricle may cause a hemodynamic picture characterized by a disproportionate elevation of right atrial pressure, compared to pulmonary artery wedge pressure, and systemic hypotension. To correct this hemodynamic derangement, routine treatment is to administer an appropriate intravenous load. We present a patient in whom the hemodynamic disturbance caused by a right ventricular infarction was corrected promptly after flow to a large marginal branch was reestablished by coronary angioplasty. http://www.travoprosteyedrops.com/ (more…)
