Effect of Progressive Muscle Relaxation on Hypertension of Aged With Myocardial Infarction

Hypertension is a third cause of mortality in the world and also has great cost of treatment for patients. Use of non pharmacologic methods similar as progressive muscle relaxation can reduce blood pressure and its complication such as myocardial infarction (MI). The study purpose determine conducted to the effect of progressive muscle relaxation on hypertensive patients with myocardial infarction.Methods & Materials: This research was quasi experimental study conducted on 40 patients who had MI with essential hypertension and were admitted to cardiac care unit (CCU) ward in Tehran Amiralam hospital during 2007. The patients were randomly divided into two groups (ex- perimental & control) and demographic information and vital sing of each patients were recorded before intervention. In experimental group progres- sive muscle relaxation technique conducted two sessions daily during 3 consecutive days and blood pressure were checked and record at the end of each session. In control group, without any intervention vital sing were checked and recorded after 20 minute. The early record vital sing and the data were analyzed with spss-software program. The age mean were 60.45±5.7 and 62.35±5.9 in experimental and control groups. The result showed in experimental group reduced mean systolic and diastolic blood pressure after the intervention which were significantly lower than control group (p<0.001) and also mean variation systolic and diastolic blood pressure pre and post application of technique also considered in control group (p<0.001). Progressive muscle relaxation (PMR) will cause reduce blood pressure in MI patients with essential hypertension. One may consider this technique (PMR) as subsidiary treat for hypertension.
