HEART SPEACIALISTS IN BANGALORE Stress echocardiography Ischaemic areas of myocardium are known to have reduced contraction compared with normal areas. This can be demonstrated by high-quality echocardiograms. A number of standard views of the heart are obtained and the wall is divided into regions that are assessed for reduced motion. The echo equipment must be designed to store rest images and to present them next to stress images on a split screen so that direct comparison can be made. The stress can be provided by exercise or dobutamine infusion. Exercise echocardiography is difficult to perform because of movement problems and there is quite high inter-reporter variability, but both techniques can approach the accuracy of sestamibi testing in experienced hands. It is not possible to obtain images of adequate quality in all patients.

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
