Beta-Adrenergic Receptor Gene Polymorphism and Response to Beta-Blocker Therapy in Korean Heart Failure Patients

2014-08-27 03:14:33 | BioPortfolio


At present, there is some clinical data for different functional response to beta-blockers associated with beta-adrenergic receptor polymorphisms. But there has been no data reported, about the incidence of beta-adrenergic receptor polymorphism and association with beta-adrenergic receptor polymorphism and response to beta-blocker therapy in Korean heart failure (HF) subjects. This single-arm, open-label, multicentric study is designed with the purpose of analysing the association between genetic polymorphism of beta-adrenergic receptor and the effects of beta-blocker (bisoprolol) in Korean HF subjects.


Heart failure impairs the quality of life of an individual and is considered to be the main cause of morbidity and mortality. Prognosis of HF subjects depends on severity, age and sex. Subjects with HF require life long treatment. Pharmacological treatment aims to improve both the quality of life and survival of HF subjects.


Primary objective:

- To analyse the association between genetic polymorphism of betaadrenergic receptor and the effects of beta-blocker (bisoprolol) in Korean HF subjects

Secondary objective:

- The frequency of polymorphism of beta adrenergic receptor in Korean HF subjects

The method involved in this study will be as follows:

- Initial evaluation of HF subjects

- Blood genomic deoxyribonucleic acid (DNA) isolation and collection

- Bisoprolol treatment as add on therapy with standard treatment for HF subject for 6 months

- Genotype of beta adrenergic receptor polymorphism

- Follow up evaluation of treated subjects

Bisoprolol will be given in a starting dose of 1.25 mg once daily for one week and if it is well tolerated, the dose will be increased to 2.5 mg for the next week and subsequently titrated up to the targeted dose of 10 mg per day.

Chronic Heart Failure With Memory and Attention Dysfunction: Old Problem, Thinking Anew.

Medical and Biotech [MESH] Definitions

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.

A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.

Disease of CARDIAC MUSCLE resulting from chronic excessive alcohol consumption. Myocardial damage can be caused by: (1) a toxic effect of alcohol; (2) malnutrition in alcoholics such as THIAMINE DEFICIENCY; or (3) toxic effect of additives in alcoholic beverages such as COBALT. This disease is usually manifested by DYSPNEA and palpitations with CARDIOMEGALY and congestive heart failure (HEART FAILURE).

Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
