Association between angiotensin-converting enzyme insertion/deletion polymorphisms and the risk of heart disease: an updated meta-analysis.
نویسندگان
چکیده
Insertion/deletion (I/D) polymorphisms of the gene encoding angiotensin converting enzyme (ACE) are a controversial risk factor for heart diseases (HDs). ACE I/D polymorphism has been reported to be associated with various cardiovascular diseases. However, some studies have presented conflicting results. In this study, we aim to explore the association between ACE I/D polymorphisms and the risk of coronary HD (CHD), coronary artery disease (CAD), and myocardial infarction (MI). A meta-analysis was conducted, which included 12,533 cases and 20,726 controls from 75 case-control studies. We performed overall analysis on the entire dataset and found that the D allele of ACE was significantly associated with increased risk of HDs in three different comparison models (dominant, recessive, and homozygote). We also performed analyses on subgroups based on ethnicity as well as disease type. Our results showed that the D allele of ACE was significantly associated with an increased risk of HDs in the Asian and European groups but not in the American group. In addition, in all three subgroups (CHD, CAD, and MI), the D allele of ACE was found to be significantly associated with increased risk of disease. Begg's funnel plots were generated to evaluate publication biases, but no obvious publication bias was found in the studies included in our meta-analysis. In conclusion, our meta-analysis demonstrated that the D allele of ACE was significantly associated with an increased risk of HDs.

The relationship between polymorphism of the angiotensin I converting enzyme (ACE) gene and chronic obstructive pulmonary disease (COPD) has been examined in many previous studies. However, their results were controversial. Therefore, we performed a meta-analysis to evaluate the relationship between the ACE gene and the risk of COPD. Fourteen case-control studies were included in this meta-anal...
متن کاملThe association of angiotensin-converting enzyme gene insertion/deletion polymorphisms with OSA: a meta-analysis.
Obstructive sleep apnoea (OSA) is an independent risk factor for hypertension. Increased angiotensin-converting enzyme (ACE) activity may be a possible promoting mechanism with different ACE insertion/deletion (I/D) genotypes influencing this activity. Studies investigating the association of ACE I/D polymorphisms with OSA have shown conflicting results. We aimed to undertake a meta-analysis of...

BACKGROUND Genetic factors in the pathogenesis of cardiomyopathies have received a lot attention during the past two decades. Angiotensin I converting enzyme (ACE) insertion/deletion (I/D) polymorphisms were found to be associated with cardiomyopathies. However, the previous results were inconsistent. The current meta-analysis aims to examine the association of ACE I/D polymorphisms and dilated...
