Premature Ventricular Complex and Diet Inflamatuar Index

The aim of this study is to evaluate differences in energy, macro- and micronutrient intakes, dietary characteristics, quality of life, and biochemical parameters between individuals with and without premature ventricular complexes. The study will include a total of 100 adults who present to the Cardiology Outpatient Clinic of Buca Seyfi Demirsoy Training and Research Hospital, comprising 50 individuals with premature ventricular complexes and 50 healthy individuals. Participants will be instructed to discontinue caffeine-containing beverages, stimulants, and medications that may affect cardiac rhythm for 72 hours prior to Holter monitoring. The diagnosis of premature ventricular complexes will be established by a specialist cardiologist. Dietary intake will be assessed using three non-consecutive 24-hour dietary recalls, including two weekdays and one weekend day. Dietary intake data will be collected by the researcher through face-to-face interviews and recorded on the study questionnaire. The Dietary Inflammatory Index (DII) and Healthy Eating Index will be calculated based on the participants' three-day dietary intake data. No additional blood samples or biochemical tests will be requested specifically for the purposes of this study. Instead, the participants' most recent biochemical parameters obtained as part of routine clinical care will be retrieved from their medical records. These parameters will include fasting blood glucose (mg/dL), glycated hemoglobin (HbA1c, %), total cholesterol (mg/dL), high-density lipoprotein cholesterol (HDL-C, mg/dL), low-density lipoprotein cholesterol (LDL-C, mg/dL), triglycerides (mg/dL), vitamin D, and other routinely assessed biochemical parameters. The results will be interpreted according to the reference ranges used by Buca Seyfi Demirsoy Training and Research Hospital. Participants' quality of life will be assessed using the 36-Item Short Form Health Survey (SF-36).
