Assessment of diet diversity and nutrient intakes in prinzmetal angina patients: A case-control study

Prinzmetal angina is a kind of angina that recognize with elevating the S-T in electrocardiogram in rest status. Diet diversity has been recommended to achieve the adequate nutrient intake.

Until now little studies investigate diet diversity and nutrients intake in prinzmetal angina patients. This case–control study was aimed to assess the association between diet diversity and prinzmetal angina incidence in Emam Khomeini hospital of Ardebil in Iran.

Using a pretested questionnaire, energy and nutrient intakes were measured using three day 24-h recall. Dietary diversity was measured by summing the number of food groups consumed over 12 weeks. Normally distributed continuous variables were reported as the mean ± SD. Independent sample t- test was used to compare differences between quantitative variables. The diet diversity scores in prinzmetal angina patients were 3 ± 0.025 and in health persons were 4.5 ± 0.053. There was a significant differences in micronutrient intakes and diet diversity score between groups (p

Increasing diet diversity in this group can be an important approaches in declining the clinical symptoms of Prinzmetal angina.
