Abstract
Background: Heart failure represents a major health problem leading to considerable
mortality morbidity. High total homocysteine concentrations have been related to increased
risk of atherosclerosis and its sequel, including coronary heart disease, cardiovascular
mortality, and stroke. Brain Natriuretic peptide is a member of a group of peptide hormones
similar in structure, used as a specific marker for diagnosing heart failure. This marker
increases gradually with the progression of the grade of heart failure.
Objective: The current study aims to measure and investigate the difference in the level of
homocysteine between patients with heart failure and without, to find the relationship
between the level of homocysteine and grade of heart failure, and to find out the correlation
between homocysteine levels with Brain Natriuretic peptide levels.
Patients and Methods: This case-control study involved 200 participants, 100 patients with
a history of chronic heart failure, and 100 control participants.A self-constructed
questionnaire form prepared to collect selected variables, the participant’s weight, height,
temperature, electrocardiography measured by trained staff, Brain Natriuretic peptide used as
a specific marker for diagnosing heart failure. Blood samples were taken early in the morning
from the patient and control groups, after at least 12-hours of fasting and a 20-minute rest.
Analysis of all samples of blood was performed in the Biochemistry Laboratory of Baqubah
teaching hospital to measure the levels of homocysteine by Human Homocysteine ELISA kit.
Results: The sample was selected homogenously in terms of age and gender. Overweight,
obesity, current and ex-smoker, history of hypertension, and history of diabetes mellitus were
significantly higher in patients with heart failure than control. The fasting mean homocysteine
level was significantly higher in patients (20.049nmol/ml) than in control (2.734nmol/ml).
