Introducing the original web score calculator GARDENIA risk score for severe coronary artery (re)stenosis

Abstract

Abstract Background/Introduction There are a large number of scores that are used for cardiovascular risk assessment and different online calculators are used to perform it. Risk prediction models provide risk estimates that can assist our decision making and improve guiding for individual clinical outcomes and personalized preventive care. Purpose GARDENIA score is designed to predict highly suspicious probability of significant coronary stenosis in patients without proven CAD or those who have already been revascularized. Methods GAR²DE²NIA is an acronym that incorporates following parameters : Gender, Age, Renal impairment, Respiratory disease, Diabetes Melittus, Echo abnormalities, ECG abnormalities, New symptoms, Ischaemia, Atrial fibrillation. The pointing scale was formed (-1 to 2) on the personal interpretation of evidence based data and is applied and designed as web calculator. The established cut-off values for the risk of significant coronary stenosis is 4. For values below 4, the probability of significant CAD is low, below 0 is very low, equal or greater than 4 significant CAD is high and above 8 is very high. Results Standard statistical formulas for sensitivity, specificity, PPN and NPV were used ( sensitivity 91,43%, specificity 73,33%, PPV 88,89, NPV 78,57). Estimated pilot sample size of 100 patients, was tested on patients cohort treated at the Institute for Cardiovascular Disease Dedinje in the year of 2022. Conclusion This original score is to be checked throughout everyday clinical practice. It is easy to use. It can help in decision making in risk stratification and further treatment of the patients who has never been to cardiologist before, those who has already been revascularized and are symptomatic again or need any kind of non cardiac surgery and the patients we have doubts about what to do next.GARDENIA score calculator
