Paper	Study sample	Results
Serdar Sever [28]	The National Audit of Cardiac Rehabilitation (NACR) registry	Receiving CABG or other treatments were associated with an increase in the odds of having new-onset depressive symptoms at the start of cardiac rehabilitation with 47 % and 24 % respectively (OR: 1.47, 95%CI: 1.25, 1.73; OR: 1.24, 95%CI: 1.08, 1.43). Patients who had heart failure were 33 % more likely to have new onset depressive symptoms (OR: 1.33, 95%CI: 1.19, 1.48).
Bai [70]	A single-center prospective cohort study was conducted at San Paolo Hospital in Milan, Italy. Study population: adult patients who were evaluated at the post-COVID outpatient service. Participants were individuals who had clinically recovered from COVID-19 and in whom virological clearance had occurred. A total of 377 patients were enrolled in the study.	A diagnosis of long COVID syndrome was made in 260/377 (69 %) patients. The most common reported symptoms were fatigue (149/377, 39.5 %), exertional dyspnoea (109/377, 28.9 %), musculoskeletal pain (80/377, 21.2 %), and “brain fog” (76/377, 20.2 %). Anxiety symptoms were ascertained in 71/377 (18.8 %) individuals, whereas 40/377 (10.6 %) patients presented symptoms of depression. Post-traumatic stress disorder (defined by a pathological IES-R score) was diagnosed in one-third of patients (85/275, 31 %).
