Brief summary
Previous research has showed a reduced lung function after cardiac surgery and this has been associated with increased mortality and morbidity. The aim of this prospective, observational study is to determine if a cheap and simple tool like HGS could be an indicator of lung function and health-related quality of life after cardiac surgery. It is hypothesized that HGS will be a simple and valid method to monitor lung function and health-related quality of life during post-hospital recovery in cardiac patients.
Interventions
Cardiovascular or cardiac diseases are range of conditions that affect the heart and blood vessels and are the leading cause of death worldwide. Cardiac diseases are regarded as “an inflammatory state”; previous studies have shown a significant relationship between high pre-operative inflammatory blood markers and increased mortality in these patients. This inflammatory reaction usually lasts up to six weeks in patients after discharge following both coronary artery by-pass graft (CABG) and valv
Cardiovascular or cardiac diseases are range of conditions that affect the heart and blood vessels and are the leading cause of death worldwide. Cardiac diseases are regarded as “an inflammatory state”; previous studies have shown a significant relationship between high pre-operative inflammatory blood markers and increased mortality in these patients. This inflammatory reaction usually lasts up to six weeks in patients after discharge following both coronary artery by-pass graft (CABG) and valvular replacement surgeries, which are the most common cardiac surgical procedures. This study will observe consenting adults who have cardiac disease and will undergo cardiac surgery. These four time-points are before the surgery, at the time of discharge from the hospital, at six weeks and at six months after surgery. Participants will be given informed consent form to read and give their consent if they are happy to participate in the study. Consenting participants' handgrip strength, lung function and health-related quality of life will be assessed at these four time points. These assessments will take approximately 30 minutes per session. Handgrip strength assessment involves the isometric contraction of the muscles of the forearm and hand using a hand dynamometer which reads off the grip strength after gripping. This test takes approximately 10 minutes per session to complete. Lung function assessment involves forced expiratory manoeuvre into a spirometer in order to measure the forced vital capacity, forced expiratory volume in one second and peak expiratory flow rate. Lung function assessment takes 10-15 mins per session to complete. Health-related quality of life will be assessed using the Short Form 36 medical outcome questionnaire. Filling out this questionnaire takes approximately 15 minutes per session to complete. Some of the demographic and clinical parameters (e.g height, weight, age, type of surgery e.t.c) will also be obtained from the participant's medical record.
