Abstract

A pivotal trial indicated that an initial invasive strategy did not improve the clinical outcomes in patients with moderate or severe ischemic heart disease and advanced chronic kidney disease (CKD) as compared with an initial conservative strategy. It is well known that contrast-induced nephropathy (CIN) is associated with worse prognosis after percutaneous coronary intervention (PCI). Minimum contrast PCI may lower the risk of CIN and improve the clinical outcomes of ischemic heart disease and advanced CKD. Here we report a case involving a 46-year-old woman with ischemic cardiomyopathy who was scheduled to start hemodialysis for end-stage diabetic nephropathy but exhibited improved renal function in accordance with the left ventricular function after PCI with an extremely low contrast dose. Accordingly, dialysis was not performed, and the patient did not require it for >2 years after coronary revascularization. The present case supports aggressive examination and revascularization for severe heart failure with an extremely low amount of contrast, even if the patient has complex coronary lesions and end-stage CKD. <Learning objective: It is important to treat with aggressive examination and revascularization for severe heart ...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
