摘要

Background

Premature coronary artery disease (PCAD) is one of the major health concerns leading to considerable death and disabilities. This study aimed to evaluate the relationship of dietary patterns with risk of PCAD.

Methods

Iran premature coronary diseases (IPAD) is a case-control study consists of 3159 participants. Obstructive CAD in ≥ 75% of at least one coronary artery or ≥ 50% in the left main artery based on coronary angiography in women under 70 and men under 60 years old was considered PCAD. The habitual dietary intake of participants was collected using a semi-quantitative validated food frequency questionnaire (SFFQ). Principal Component Analysis (PCA) was used to extract dietary patterns.

Results

Three main dietary patterns including healthy, Western and high-fat, high-sugar were identified. Patients categorized in the last tertile of the healthy dietary pattern had a decreased risk of PCAD (OR = 0.77, 95% CI: 0.64–0.93), while those in the top tertile of Western (OR = 2.38, 95 CI:1.97–2.86) and High-fat simple carbohydrate (HFSC) (OR = 3.10, 95% CI:2.57–3.75) diets had increased risk of PCAD.

Conclusions

A healthy dietary pattern was significantly related to a decreased risk of PCAD presence, whereas Western and HFSC diets were connected to a higher risk of PCAD.
