            This quasi-experimental research aimed to examine the effect of health behavior modification program on the blood pressure of older persons after percutaneous transluminal coronary intervention by applying the protection motivation theory. The sample was 48 older persons after percutaneous transluminal coronary intervention (PCI) with systolic blood pressure (SBP) greater than 130 mmHg or with diastolic blood pressure (DBP) more than 80 mmHg. in cardiac care unit at the Rajavithi hospital. They were divided into the experimental and the control group of 24 persons. The participants were paired-match by age, gender, and type of antihypertensive drug received. The experimental group underwent the program designed by the researcher for 6 weeks. The experimental instrument was health behavior modification program. Data was collected using blood pressure record form. Data were analyzed using descriptive and t-test analysis.
            The results revealed that after participating the health behavior modification program, the experimental group had significantly lower mean systolic and diastolic BP than before joining the program (p < .05). The experimental group had significantly lower mean systolic and diastolic BP than those in the control group (p < .05). The results of this research indicated that the program could produce good clinical outcomes resulting in blood pressure control among older persons after percutaneous transluminal coronary intervention.
