Insights
Inherited thrombophilia, genetic predispositions to blood clots, is more common in patients with arterial diseases like stroke, heart attack, and peripheral artery disease. Testing may be beneficial for certain patient groups.
Area of Science:
- Cardiovascular Genetics
- Thrombosis Research
- Molecular Epidemiology
Background:
- The association between inherited thrombophilia and arterial diseases remains unclear.
- This study systematically reviewed and meta-analyzed the prevalence of inherited thrombophilia in patients with cerebrovascular disease (CVD), coronary heart disease (CHD), and peripheral artery disease (PAD).
Purpose of the Study:
- To determine the pooled prevalence and odds ratios of specific inherited thrombophilia gene polymorphisms in patients with CVD, CHD, and PAD.
- To identify potential associations between inherited thrombophilia and arterial disease risk.
Main Methods:
- A systematic review and meta-analysis of studies published up to February 2022.
- Searched MEDLINE and EMBASE databases.
- Evaluated Factor V Leiden (G1691A), prothrombin (G20210A), MTHFR (C677T/A1298C), and PAI-1 (4G/5G) gene polymorphisms.
- Calculated pooled prevalences (PPs) and odds ratios (ORs) using a random-effects model.
Main Results:
- Included 377 studies with 98,186 patients and 108,569 controls.
- Found increased pooled prevalences of thrombophilia in patients across CVD, CHD, and PAD compared to controls.
- Identified significant odds ratios for certain polymorphisms, particularly homozygous Factor V Leiden (G1691A) and prothrombin (G20210A) in CVD, and PAI-1 4G/4G in PAD.
- Observed variations in prevalence and odds ratios based on age and geographic region.
Conclusions:
- Patients with arterial diseases exhibit a higher prevalence and odds of certain inherited thrombophilias.
- Consideration of thrombophilia testing may be warranted for specific patient subgroups, especially those with a strong family history or from regions with higher prevalence.
Introduction:
The role of inherited thrombophilia in arterial disease is uncertain. We performed a systematic-review and meta-analysis of inherited thrombophilia in cerebrovascular (CVD), coronary heart (CHD), and peripheral artery disease (PAD) patients.
Materials And Methods:
MEDLINE and EMBASE were searched up to February 2022. Pooled prevalences (PPs) and odds ratios (ORs) with 95 % confidence intervals (95%CI) were calculated in a random-effects model. Factor V Leiden (G1691A), prothrombin (G20210A), MTHFR C677T/A1298C and PAI-1 4G/5G were evaluated.
Results:
377 studies for 98,186 patients (32,791 CVD, 62,266 CHD, 3129 PAD) and 108,569 controls were included. Overall, 37,249 patients had G1691A, 32,254 G20210A, 42,546 MTHFR C677T, 8889 MTHFR A1298C, and 19,861 PAI-1 4G/5G gene polymorphisms. In CVD patients, PPs were 6.5 % for G1691A, 3.9 % for G20210A, 56.4 % for MTHFR C677T, 51.9 % for MTHFR A1298C, and 77.6 % for PAI-1. In CHD, corresponding PPs were 7.2 %, 3.8 %, 52.3 %, 53.9 %, and 76.4 %. In PAD, PPs were 6.9 %, 4.7 %, 55.1 %, 52.1 %, and 75.0 %, respectively. Strongest ORs in CVD were for homozygous G1691A (2.76; 95 %CI, 1.83-4.18) and for homozygous G20210A (3.96; 95 %CI, 2.05-7.64). Strongest ORs in CHD were for homozygous G1691A (OR 1.68; 95%CI, 1.02-2.77) and G20210A (heterozygous 1.49 95%CI, 1.22-1.82; homozygous 1.54 95%CI, 0.79-2.99). The OR for PAI-1 4G/4G in PAD was 5.44 (95%CI, 1.80-16.43). Specific subgroups with higher PPs and ORs were identified according to age and region.
Conclusions:
Patients with arterial disease have an increased prevalence and odds of having some inherited thrombophilia. Some thrombophilia testing may be considered in specific subgroups of patients.
