The Relationship Between Body Mass Index And Index of Cardiac Electrophisiological Balance

Öz

Background: The relationship between obesity and changes in electrocardiographic wave duration were demonstrated previously. The aim of our study was to examine the relationship between body mass index (BMI) and index of cardiac electrophysiological balance (ICEB)/corrected index of cardiac electrophysiological balance (ICEBc). Materials and Methods: A total of 353 consecutive patients with no comorbidities other than obesity admitted to an outpatient cardiology clinic between September and November 2023 were enrolled in the study. The patients were divided into 5 groups according to their BMI as follows: BMI <20 kg/m2 was defined as group 1, BMI 20–24.99 kg/m2 as group 2, BMI 25–29.99 kg/m2 as group 3, BMI 30–39.99 kg/m2 as group 4 and BMI >40 kg/m2 as group 5. Electrocardiographic parameters ICEB/ICEBc levels were compared among the groups. Results: The mean age of the participants was 32.6±10.61 years, and 199 (56.4%) were female. The mean ICEB values of groups were 4.36±0.53, 4.17±0.53, 4.04±0.52, 4.27±0.55 and 4.18±0.47, respectively and there was a significant difference among the groups (p=0.014). In addition, the mean ICEBc values were 5.03±0.69, 4.81±0.63, 4.6±0.56, 5.05±0.68, and 5.05±0.52, respectively and there was a significant difference among the groups (p<0.001). It was found that low and high BMI groups were associated with a significant increase in ICEB and ICEBc values in the subgroup analyses. Conclusions: As a result of our study, it was observed that low and high BMI values may be associated with an increase in ICEB and ICEBc values. It should be kept in mind that ICEB and ICEBc values may be high in cardiac evaluation in relatively thin and obese individuals.

Vücut Kitle İndeksi ile Kardiyak Elektrofizyolojik Denge İndeksi Arasındaki İlişki

Öz

Amaç: Obezite ile elektrokardiyografik dalga sürelerindeki değişiklikler arasındaki ilişki daha önce gösterilmiştir. Vücut kitle indeksi (BMI) ile kardiyak elektrofizyolojik denge indeksi (ICEB)/düzeltilmiş kardiyak elektrofizyolojik denge indeksi (ICEBc) arasındaki ilişkiyi incelemeyi planladık. Materyal ve metod: Eylül-Kasım 2023 tarihleri arasında obezite dışında ek hastalığı olmayan toplam 353 kişi (199 kadın, 154 erkek, ortalama yaş 32,6 ± 10,611 yıl) çalışmaya dahil edildi. Tüm hastalar BMI'a göre 5 gruba ayrıldı. BMI<20 kg/m2 olan katılımcılar grup 1 olarak tanımlandı, BMI=20-24,99 kg/m2; grup 2, BMI=25-29,99 kg/m2; grup 3, BMI=30-39,99 kg/m2; grup 4 ve son olarak BMI>40 kg/m2 ise grup 5 olarak tanımlandı. Bulgular: Yaş ortalaması 32,6±10,61 olup toplam kadın katılımcı sayısı 199 (%56,4) idi. Grupların ortalama BKİ'si sırasıyla 18,72±1,25, 22,84±1,48, 26,86±1,36, 34,65±3,24, 44,63±4,11 (p<0,001) idi. Grupların ortalama ICEB'si 4,36±0,53, 4,17±0,53, 4,04±0,52, 4,27±0,55, 4,18±0,47 (p=0,014), ICEBc ise 5,03±0,69, 4,81±0,63, 4,6±0,56, 5,05±0,68, Sırasıyla 5,05±0,52 (p<0,001). BMI ile QTc intervali, ICEB ve ICEBc'de anlamlı artış gözlenirken, QT intervalinde anlamlı bir değişiklik gözlenmedi. Sonuç: Çalışmamız obezitenin aynı zamanda ICEB ve ICEBc değerlerinde de anlamlı artışa neden olduğunu gösterdi. Çalışmamız ışığında ICEB ve ICEBc değerlerinin obez bireylerde kötü kardiyak sonuçların öngörücüsü olabileceği gösterilmiştir.
