Study of Polymorphisms of RAAS and MMPs in Acute Heart Failure

Completed

• Conditions: Acute Heart Failure

• Registration Number: NCT02170961
• Lead Sponsor: University of Monastir

Brief Summary

this study aim to investigate the:

* association of RAAS polymorphisms and AHF

* association of MMP 3 and 12 polymorphisms and AHF

Detailed Description

Heart failure can be defined as a complex clinical syndrome that results from any structural or functional disorder of the heart, with impairment of ability to fill the ventricles or eject blood. The main event of the IC is dyspnea and fatigue, which limit exercise tolerance and induces water retention.

The renin angiotensin aldosterone system governs the salt and water homeostasis in the body. Renin is a proteolytic enzyme secreted by the juxtaglomerular apparatus of the kidney (area near the glomeruli). Renin has no direct action on the organism, but that is part of the renin-angiotensin system or the renin-angiotensin-aldosterone system is known.

To date, few published studies have examined the association between the polymorphism AGT M235T \* and cardiac dysfunction; and available results are contradictory. What is not known yet is the ratio of this polymorphism with the prognosis of heart failure.

Primary Outcome Measures

Name	Time	Method
mortality RAAS	one year	the association between RAAS genes polymorphisms and mortality at one year average

Secondary Outcome Measures

Name	Time	Method
association between MMP polymorphism and AHF	at admission (average of 1 day)	the association between the diagnosis of AHF (based on clinical, BNP, and echocardiographic finds) and the MMP genes polymorphism is studied at patient admission for acute dyspnea.
association between RAAS polymorphism and AHF	at admission (an average of 1 day)	the association between the diagnosis of AHF (based on clinical, BNP, and echocardiographic finds) and the RAAS genes polymorphism is studied at patient admission for acute dyspnea.
