The effect of music: on cardio respiratory physiology of asymptomatic individuals and the effect of music on the disease condition and the quality of life in patients heart disease [stable angina patients]

INTERVENTION: Study 1 Community based experimental study Study 2 Randomised controlled trial (Clinical trial). Listening to a piece of music for 20 minutes Study 2 Listening to a piece of music twice a day for 20 minutes each for one month CONDITION: Cardio respiratory physiology and chronic stable angina PRIMARY OUTCOME: Study 1 Changes in Diastolic Blood pressure Study 2 The time taken to 1 mm ST segment depression in exercise ECG SECONDARY OUTCOME: Study 1 •Blood pressure •Pulse rate •Respiratory rate Study 2 •Clinical Profile: State of Ischemia •Exercise duration (s) •Stage at which patient stops the test •Maximal heart rate during exercise (beats. Min‐1) •Time until 1 mm ST segment depression •Maximal ST segment depression •Double product (Heart rate/min X Blood pressure mmHg) •Symptom of ischemia •Quality of life INCLUSION CRITERIA: Study 1 Both male and female individuals between 45 to 65 years of age The individuals who are not having heart disease and hypertension and who are not being on any long term treatment The individuals whose pulse rate, blood pressure and heart sounds are within normal range The individuals who don’t have hearing impairment Study 2 Clinically diagnosed chronic stable angina patients confirmed by exercise ECG using bruce protocol during the study period Patients with no other heart diseases Both male and female patients between 45 to 65 years of age Patients whose clinical condition is stable and who do not require frequent change of the treatment Patients who can perform exercise ECG test Patients who like to participate in the study
