Additionally, patients with New York Heart Association (NYHA) Grade II accounted for 33.5%, and Grade III accounted for 45.7%. Table 1 shows the baseline demographics, clinical and procedural characteristics of the whole patients. As shown, compared with patients without CI-AKI, those with CI-...
nyha class iii or iv. the svm-ga model was proposed to classify the grade of patients with heart failure and calculate the importance of features. the accuracy, positive predictive value, and recall of the proposed svm-ga model were 91.49, 94.25, and 93.6%, respectively. tsai and morshed ...

摘要: Background Heart failure (HF) is a major problem in the long-term follow-up of adolescents and adults with congenital heart disease (ACHD) after cardiac surgery. The functional status of ACHD may be assessed in terms of the NYHA classification or the Ability index (ABILITY)....
The New York Heart Association (NYHA) classification is often used as a measure of a patient's response to CRT. Identifying NYHA class for heart failure patients in an electronic health record (EHR) consistently, over time, can provide better understanding of the progression of heart failure ...

Conclusions The NYHA classification is not a sensitive measure of health-related quality of life, and its use as an outcome measure, although providing some insights, may result in misleading findings. The NYHA classification should not be used as the sole outcome measure. (Am Heart J 1998;135...
