High Serum Uric Acid is Highly Associated with a Reduced Left Ventricular Ejection Fraction Rather than Increased Plasma B-type Natriuretic Peptide in Patients with Cardiovascular Diseases.

ABSTRACT: High serum uric acid (UA) has been reported to be associated with left ventricular (LV) dysfunction; however, the relationship between UA and plasma B-type natriuretic peptide (BNP), a sensitive biomarker of heart failure, is still unclear. This study investigated their relationship to provide an accurate assessment of high UA. The study patients consisted of 3,077 subjects who underwent cardiac catheterization because of various cardiovascular disorders. Since the explanatory factors of multiple regression analysis were mostly confounding with each other, subgroup analysis was performed by quartering the study population using the respective risk factors and by covariance structure analysis. This analysis revealed that UA was almost always well associated with a reduced LV ejection fraction (LVEF), but generally not with BNP. UA was significantly associated with BNP in lean aged females, but not in obese adolescent males, although LVEF was significantly reduced in response to a high UA in both groups. A high UA is a direct risk factor for cardiac dysfunction from the perspective of BNP; however, augmentation of BNP in response to a high UA would likely be restricted among obese adolescent males. On the other hand, the observed LV systolic dysfunction, such as LVEF, reflects a high UA on an almost constant basis.

Project description:Background Trastuzumab is life-extending therapy for breast cancer patients overexpressing the human epidermal growth factor receptor 2 ( HER 2+), but has known cardiotoxic risk. We sought to determine if trastuzumab can be administered to patients with reduced baseline cardiac function at no higher cardiotoxicity risk than in those with normal cardiac function at baseline. Methods and Results We performed a retrospective study of women treated with trastuzumab for human epidermal growth factor receptor 2 breast cancer at Mayo Clinic Rochester between January 1, 2000 and August 31, 2015 with pre- and on-therapy echocardiograms available for review. A left ventricular ejection fraction (LVEF) <53% was considered abnormal, and a ≥10% decline in LVEF as evidence of cardiotoxicity based on the criteria of the American Society of Echocardiography. A total of 428 women were identified; 408 had a normal cardiac function ( LVEF 63.4±5%) and 20 had an impaired cardiac function ( LVEF 45.4±7%) before trastuzumab. Seven women (35%) with reduced LVEF at baseline had a ≥10% reduction in LVEF , compared with 179 (43.9%) of those with normal LVEF before trastuzumab initiation ( P= NS ). Symptomatic heart failure developed more often in patients with reduced versus normal baseline LVEF (25% versus 4.2%, P<0.05). After adjusting for patient age and breast cancer disease stage, survival rates over 5 years from time of diagnosis were found to be lower for patients with reduced baseline LVEF compared with patients with normal baseline LVEF ( P<0.001); the adjusted proportion of patients surviving at 5 years for those with low LVEF at baseline was 79% and for those with normal LVEF was 93%. Conclusions Women undergoing trastuzumab therapy for breast cancer with impaired baseline cardiac function experience no higher risk of LVEF decline, but more frequently develop symptomatic heart failure. While trastuzumab could be considered, these patients should be co-managed by a cardiologist.
