The treatment of patients with ischaemic cardiomyopathy is still problematic. The choice of revascularization of these patients especially who have different degrees of viability is not widely implemented due to confusion about its benefit. This work aimed to evaluate prospectively the response of left ventricular function to low as well as high dose dobutamine in patients with ischaemic cardiomyopathy showing different degrees of viability to see if there is an improved resting left ventricular ejection fraction after coronary angioplasty. This book is intended primarily to the interventional cardiologists,general cardiologists and internists who are interested in this subject.
