A simple algorithm for a clinical step-by-step approach in the management of hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease with an autosomal dominant pattern and a reported prevalence of about 0.2%. In this review, we present a simple algorithm for the management of first diagnosed HCM patients. Initially, the clinical examination, medical and detailed family history and the ECG are essential. The etiological diagnosis of left ventricular hypertrophy is important in order to differentiate HCM due to sarcomeric genes mutation from other phenocopies, such as cardiac amyloidosis. The next step consists of the cardiovascular imaging and ambulatory electrocardiography. Cardiopulmonary exercise testing may also be considered if available. All of the above provide evidence for the critical step of the risk stratification of patients for sudden cardiac death. The therapeutic strategy, with respect to obstructive and nonobstructive disease, arrhythmias and end-stage HCM is also described.

Background: Cardiovascular disease is the major cause of death in dialysis patients, as well as in kidney transplant patients. Assessment of cardiovascular risks of renal transplant candidates to prevent or slow the progression of cardiovascular abệnh nhânormalities. Aim: 1) Evaluating cardiovascular risk factors, electrocardiographic and echocardiographic abnormalities in renal transplant candidates. 2) Identifying the correlation between cardiac morphological parameters with a number of factors involved. Subjects and Methods: We assessed 57 patients (73.7% male, mean age 32.4±8.8) with end-stage renal disease waiting for renal transplantation at Cho Ray Hospital between Jan 2012 and Jan 2013. All patients received a physical examination, blood pressure measurement, Hb, blood glucose test, lipid profile, ECG, echocardiography. Results: The percentage of hypertension was 98.2%, smoking (69.2%), dyslipidemia 40.4% and diabetes 12.3%. All patients had sinus rhythm, left ventricular hypertrophy 61.4% in ECG. Pericardial effusion 5.3%, mitral valve insufficiency 56.1%, aortic valve insufficiency 12.3%, left ventricular hypertrophy 94.7% in echocardiography. IVSd, LVPWd, LVMI positively correlated with kidney failure time (p <0.01, p<0.001), with DBP and SBP (p <0.05) and the degree of anemia (p <0.05). Percentage the degree of hypertension associated with proportion of left ventricular hypertrophy (p <0.05). Conclusions: Identification of cardiovascular risk factors for the prevention or intervention to reduce mortality in renal transplantation. Keywords: Cardiovascular risk factors, end-stage chronic renal failure, renal transplantation.
