The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. |
At baseline, 30 days, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years | |
Secondary | The change in depression status from baseline for each subject assessed by the Patient Health Questionnaire (PHQ)-8 questionnaire. | Depression status will be assessed by the PHQ-8 questionnaire. The PHQ-8 is a series of 8 questions will four possible answers each. The questions focus on over-all well-being as well as daily habits. The higher the score the more the patient is likely to be depressed. Depression status will be determined at the time of the procedure, at 30 days, 6 months, 12months and then annually up to 5 years. | At baseline, 30 days, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years | |
Secondary | The change in anxiety status from baseline for each subject. will be assessed by the Generalized Anxiety Disorder (GAD)-7 questionnaire. | Anxiety status will be assessed by the GAD-7 questionnaire. The GAD-7 is a series of 7 questions will four possible answers each. The questions focus on over-all well-being as well as daily habits. The higher the score the more the patient is likely to be anxious. Anxiety status will be determined at the time of the procedure, at 30 days, 6 months, 12months and then annually up to 5 years. | At baseline, 30 days, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years | |
Secondary | The proportion of subjects that experience a series of procedural outcomes as assessed by the site and adjudicated by the CEC. | Procedural outcomes will be categorized into the following: Reclassification from pre-procedure diagnosis (including non-cardiac chest pain); Completion of the interventional diagnostic procedure without device-related serious adverse events or major angiographic complications; Frequency of major angiographic complications (device-related coronary artery dissection [greater than type C], slow or no flow, or perforation) | Up to 48 hours after the procedure |
