Use the ACS symptom checklist and Memorial symptom assessment scale-heart failure to estimate ASCVD-related symptoms. The ACS Symptom Checklist is a validated instrument comprising 13 items designed to assess symptoms associated with ACS. Participants are asked to indicate whether each symptom is present (1) or absent (0). Each symptom is analyzed individually, and there is no composite score. The Memorial Symptom Assessment Scale-Heart Failure comprises 32 items, categorized into three subscales: physiological symptoms (n=21), psychological symptoms (n=6), and heart failure symptoms (n=5). Symptoms are rated on presence, frequency, severity, and distress, with frequency, severity, and distress rated on a Likert scale of 1-4, where higher scores indicate higher frequency, severity or greater distress.

The scale was developed by the Boston Health Research Institute, based on the Rand Corporation Health Insurance project, to assess the degree of health change in the past year. In 1996, the International Quality of Life Evaluation Organization recommended the use of SF-36 for quality of life measurement. There are 36 items in the scale, of which item 2 is self-reported health change and does not participate in the score calculation of the scale. The remaining 35 entries are divided into eight dimensions, Including physical functioning, role-physical, bodily pain, and general health perceptions, vitality, social functioning, role-emotional, and mental health.
