The highly impactful International Study of Comparative Health Effectiveness With Medical and Invasive Approaches ( ISCHEMIA ) trial investigated the effectiveness of invasive (INV) versus conservative (CON) strategies for managing stable coronary artery disease.

Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults. Discussion on pediatric exercise testing. In a child with suspected sinus node dysfunction, chronotropic incompetence from sinus node dysfunction can be assessed by exercise testing.

The images demonstrate a moderately extensive, mildly severe reversible defect in the mid and distal anterior/anterolateral wall consistent with ischemia. Which of the vessels is likely the culprit vessel causing the ischemia? The patient also had a cardiac CT for calcium scoring pictured below. The technologist performs a MUGA scan.

Transient ischemia may occur while negotiating tight stenosis or small vessels. But these major complications occur usually during interventions rather than diagnostic IVUS evaluations. Vasospasms are usually transient and respond to intracoronary nitroglycerine.

Absence of brachiocephalic artery occlusion which will increase the risk of intraprocedural cerebral ischemia 3. Brachiocephalic artery diameter 8 mm or more on CT so that 18-F sheath could be inserted and blood flow could occur through the gap between the sheath and the vessel 2. No calcifications in the artery causing vascular stenosis.

That is, there is renal ischemia due to clogging of capillaries, which leads to increased erythropoietin secretion and this causes decompensated erythrocytosis. And it was described from the very first report of Eisenmenger syndrome. That has already been discussed. Decompensated erythrocytosis is something which we see very often.

Automatic ventricular tachycardia can occur in acute ischemia, electrolyte imbalance and with increased sympathetic tone. Ventricular tachycardia can be classified according to the mechanism of genesis into reentrant, automatic and triggered activity. Triggered activity can be early and delayed afterdepolarization.

ST segment elevation in aVR in proximal LAD occlusion before first septal is thought to be due to transmural ischemia of the basal part of the septum. ST elevation in aVR greater than or equal to that in V1 distinguished left main stenosis from left anterior descending coronary artery stenosis with 81% sensitivity and 80% specificity.

They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia. These are the conditions which have to be considered or excluded as they can sometimes manifest Brugada pattern on ECG.
