The SQ_Heart has been designed as an observational study that evaluates the difference in sleep quality between 11 patients with VAD (Ventricular Assisted Device) and 98 Cardiotransplant patients.

The Primary objective of the SQ_Heart study is to evaluate the significant difference in sleep quality between patients with VAD (Ventricular Assisted Device) and cardiotransplant patients, using the Pittsburgh scale Sleep Quality Index (PSQI), with a cut-off of > 5 for poor sleepers.

Patients, to be enrolled, must provide:

• Age ≥ 18 and < 90;
• Cardiotransplant patients, with VAD or non;

• subjects able to sign informed consent.

All the patients will have to complete some questionnaires:

• questionnaire about the diagnosis of pathology and lifestyle;
• questionnaire about the perceived quality of sleep through the use of Pittsburgh Sleep Quality (PSQI);
• questionnaire about the perceived quality of life (Euro Quality of Life 5D-5L).

Questionnaires are necessary for the data collection for the study.

Inclusion Criteria:

• Age ≥ 18 and < 90;
• Cardiotransplant patients, with VAD (Ventricular Assisted Device) or non;
