    Golden ratio in congestive heart failure: a promising proportion for prognosis and decompensation
    (2020) Yetkin, Ertan; Özturk, Selçuk; Çuğlan, Bilal; Turhan, Hasan
    The article published by Kowalczys et al. [1] was read with great enthusiasm and interest. Briefly, the prognostic value of daytime heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure (BP), and their multiplication products and ratios was assessed in congestive heart failure (CHF) patients. Accordingly, it was found that daytime DBP and products including HR × DBP and HR × SBP may be valuable risk stratification factors for predicting death and decompensation in stable patients [1]. Beyond the prognostic implication of HR, BP and their products in patients with stable CHF, attention was paid to the value of SBP and DBP itself, in terms of the golden ratio. In the study population, Kowalczys et al. [1] found mean daytime SBP and DBP of patients with stable CHF as 114 mmHg and 70 mmHg, respectively. The ratio of SBP to DBP gives 1.62, which is very close to the golden ratio as described previously by the famous mathematicians Euclid and Fibonacci [2]. In addition, it is also noteworthy to calculate the ratio of SBP to DBP in patients with decompensated (107.0/60.7 mmHg) and non-decompensated (115.3/72.1 mmHg) status during the follow-up period. SBP/DBP in patients without decompensation is 1.59; whereas it is 1.76 in decompensated patients, which shows a distinct deviation from the golden ratio.
