THE BEST CARDIOLOGISTS IN YELAHANKA Indications for coronary angiography 1 Angina not responding to medical treatment in a patient without contraindications (e.g. extreme old age—usually older than about 85 these days—or severe co-morbidities) to cardiac surgery or angioplasty. 2 Continuing chest pain whose cause is not clear despite non-invasive investigations. The procedure may well be worthwhile if it reveals normal coronary arteries and prevents a patient being treated unnecessarily with more and more anti-anginal drugs. Non-invasive investigations are more often equivocal in women, and more women than men are found to have normal coronaries at angiography. 3 Preparation of a patient older than 35 or so for some other cardiac surgery (e.g. valve replacement). The surgeon needs to know whether significant coronary disease is present so that coronary grafting can be performed at the time of valve surgery. Otherwise, patients are at risk of ischaemic problems in the post-operative period. 4 Diagnosis of cardiomyopathy (p. 267) by excluding coronary artery disease and infarction as the cause of angina or cardiac failure. These patients may benefit from revascularisation if significant coronary disease is also present (‘ischaemic cardiomyopathy’). 5 Investigation of patients following myocardial infarction. Routine transfer to a centre with angiographic facilities after successful thrombolytic treatment is a grade D recommendation. There is no proof that a patient without continuing ischaemia has an improved prognosis when angiography and revascularisation are carried out routinely after infarction. The Open Artery Trial results suggest there is no benefit compared with optimal medical treatment for patients without ischaemic symptoms in having an occluded vessel opened five days or more after an infarction. However, spontaneous or induced ischaemia (by modified stress testing or perfusion imaging) leads to a grade B recommendation for angiography and intervention. The management of post-infarct patients is definitely easier if the coronary anatomy is known, and many units adopt the policy of early (within a week) angiography of infarct patients without contraindications to revascularisation. 6 Non-ST elevation acute coronary syndromes (p. 156). 7 Acute myocardial infarction in a unit where primary angioplasty can be performed

Indications for Hemodynamic Monitoring in Patients with STEMI Management of complicated acute myocardial infarction Hypovolemia versus cardiogenic shock Ventricular septal rupture versus acute mitral regurgitation Severe left ventricular failure Right ventricular failure Refractory ventricular tachycadia Differentiating severe pulmonary disease from left ventricular failure Assessment of cardiac tamponade Assessment of therapy in selected individuals Afterload reduction in patients with severe left ventricular failure Inotropic agent therapy Beta-blocker therapy Temporary pacing (ventricular versus atrioventricular) Intraaortic balloon counterpulsation Mechanical ventilation
It may also improve arterial oxygenation by reducing pulmonary vascular congestion DIURETICS. Mild heart failure responds well to diuretics such as furosemide, Dose - 10 to 40 mg, repeated at 3- to 4-hour intervals if necessary. It reduces pulmonary capillary pressure reduces dyspnea. Decreased LVDV↓ LV wall tension - ↓ myocardial oxygen requirements and may lead to improvement of contractility and augmentation of the ejection fraction, stroke volume, and cardiac output. The reduction of elevated left ventricular filling pressure may also enhance myocardial oxygen delivery by diminishing the impedance to coronary perfusion attributable to elevated ventricular wall tension. .
