Effect of Pulmonary Rehabilitation Program on Patients With Acute Ischemic Stroke, Mortality and Disability

2019-10-07 08:56:55 | BioPortfolio


Severe stroke remains an important cause of mortality and morbidity, despite advances in disease management, acute treatment and secondary measures. Among all post-stroke complications, pneumonia constitutes a major complication with a strong impact on morbidity and mortality. Research also showed that a reduction in respiratory muscle and abdominal muscle strength contributed to pulmonary and respiratory dysfunction following a stroke. Low respiratory muscle function decreases the efficacy of rehabilitation because it leads to exercise intolerance in stroke patients. Thus, special exercise programs are needed to improve the pulmonary function and respiratory muscle strength of stroke patients The aim of pulmonary rehabilitation program is to enhance respiratory muscle resistance during breathing, thereby improving respiratory function. Previous studies demonstrated that pulmonary rehabilitation programs improved respiratory functions in cardiac disease and chronic obstructive pulmonary disease patients


The study will be conducted on 80 adult patients with Acute Ischemic Stroke.

Inclusion criteria:

- Adult (≥18 years old).

- With Acute Ischemic Stroke.

Exclusion criteria:

- Hemorrhagic stroke.

- GCS < 7 on admission.

- Clinical signs of infection on admission.

- Significant pulmonary disease, angina, myocardial infarction or acute heart failure within three months.

For every eligible patient the following data will be collected:

- Demographic data including age & sex.

- Vital signs.

- Glasgow Coma Score on admission after primary respiratory and hemodynamic stabilization.

- Stroke severity on admission assessed by the National Institute of Health Stroke Scale (NIHSS).

- All patients will undergo a CT scan of the brain on admission. Diagnostic procedures such as Doppler ultrasound of the carotid arteries, MRI, and echocardiography will be ordered if deemed necessary by the treating physician.

- Stroke subtype classification utilizing both the TOAST (Trial of ORG 10172 in Acute Stroke Treatment) method and The Oxfordshire Community Stroke Project.

- Pre-existing comorbid conditions (any treatment and/or patient's self-report): Hypertension, Diabetes Mellitus, Atrial Fibrillation, COPD, CHF, and Current Smoking.

- Evidence for any type of dysphagia documented by a standardized dysphagia screening test.

- Laboratory data: White Blood Cell (WBC) Count, C-reactive Protein (CRP), and Blood Glucose will be done daily.

Grouping The patients will be randomized into 2 groups by conventional method of randomization where patients in group 1 (control group) will be selected in odd numbers and those in group 2 (patients receiving pulmonary rehabilitation program) will be selected in even numbers.

Stroke management Group 1: (Control group) 40 patients will receive Stroke management based on the guidelines of the American Heart Association/American Stroke Association.

Group 2: (Patients receiving pulmonary rehabilitation program) 40 patients will receive Stroke management based on the guidelines of the American Heart Association/American Stroke Association in addition to pulmonary rehabilitation program.

Enrolled patients will be prospectively followed up for:

1. Primary outcome:

• The diagnosis of pneumonia within the first 7 days after admission. (Diagnosis will be made according to modified criteria of the CDC

2. Secondary outcome:

- In-hospital or 30 days mortality.

- Modified Rankin Scale (mRS) at one month.

Restoration of functions to the maximum degree possible in a person or persons suffering from a stroke.

A morpholine and thiophene derivative that functions as a FACTOR XA INHIBITOR and is used in the treatment and prevention of DEEP-VEIN THROMBOSIS and PULMONARY EMBOLISM. It is also used for the prevention of STROKE and systemic embolization in patients with non-valvular ATRIAL FIBRILLATION, and for the prevention of atherothrombotic events in patients after an ACUTE CORONARY SYNDROME.

A condition of lung damage that is characterized by bilateral pulmonary infiltrates (PULMONARY EDEMA) rich in NEUTROPHILS, and in the absence of clinical HEART FAILURE. This can represent a spectrum of pulmonary lesions, endothelial and epithelial, due to numerous factors (physical, chemical, or biological).
