Brief Summary

In this quasi-experimental study, which involved having patients who had experienced a MI engage in 50 minute green walks three times a week for 12 weeks, the following hypotheses were tested: High-intensity interval green walking has the effect of reducing the anthropometric measurements of patients undergoing MI. High-intensity interval green walking has the effect of reducing LDL, triglyceride, total cholesterol levels and increasing HDL levels of patients who have with MI. High-intensity interval green walking has a positive effect on the perception of disease of patients who have undergone MI. High-intensity interval green walking has an effect on improving the quality of life of patients with MI. Research Question 1: What is the impact of green walking on the body mass index (BMI) of patients with MI? Research Question 2: How does green walking influence blood lipid levels (triglycerides, LDL, total cholesterol, and HDL) in patients with MI? Research Question 3: What is the effect of green walking on the perception of the disease in patients with MI? Research Question 4: How does green walking affect the quality of life of patients with MI? 2 Groups: Green walking group and control group

Outcome Measures

Primary Outcomes (8)

• The Structured Patient Information Form

  Developed by the researcher after reviewing the literature, the form consisted of two parts. The first part included six questions to determine the sociodemographic characteristics of the patients (gender, age, education level, marital status, employment status, and occupation), and the second part included a total of 10 questions, including four questions to determine the characteristics related to the disease (when MI occurred, presence of MI risk factors, etc.).

  1 day before the study

• The Blood Lipids and BMI Monitoring Form

  This form was developed by the researcher in line with the literature. It included blood lipids (HDL, LDL, Triglyceride and Total cholesterol), height (cm), and weight (kg) measurements of the patients. BMI was calculated by dividing body weight by the square meter of height (BMI=kg/m2). The blood lipid measurement results of the patients (1st-week measurement; 6th-week interim measurement; 12th-week measurement) were obtained from the patient file by the researcher during Cardiology Outpatient Clinic visits.

  1 day before the study

• The Brief Illness Perception Questionnaire (Brief IPQ)

  This scale was developed by Broadbent et al. in 2006. The nine-item section of the scale defines the emotional and cognitive aspects of illness perception. Each item in the scale consists of open-ended questions and is scored between 0 and 10. In the last item, the individual is asked to indicate three factors that he/she thinks are the cause of his/her illness. These items include consequences, timeline, personal control, treatment control, identity, illness concern, coherency, and emotional response, respectively. The highest and lowest scores are 80 and 0. On the scale, the positive reaction consists of the score given to three sub-dimensions (3rd, 4th, and 7th) with a score between 0-10, and the negative reaction consists of the score given to five sub-dimensions (1st, 2nd, 5th, 6th, and 8th). Sub-dimension (1st, 2nd, 5th, 6th, and 8th) items are reverse scored. High scores indicate a negative perception of illness.

  1 day before the study

• The Myocardial Infarction Dimensional Assessment Scale (MIDAS)

  The Turkish validity and reliability of the MIDAS, devised by David Thompson et al. in 2002, were examined by Uysal et al. (2008), and the Cronbach alpha value of the scale was calculated as 0.83. The scale includes 35 items and seven sub-dimensions, including physical activity, insecurity, emotional reaction, dependency, diet, concerns over medication, and side effects. The scoring of the scale is between 0 and 100. A high score on the scale indicates poor health status.

  1 day before the study

• Weight

  Weight was measured with a medical scale with a hospital-calibrated height scale while the patients were fasting, after removing their thick clothes and before the physician examination.Then it was recorded The Blood Lipids and BMI Monitoring Form.

  1 day before the study

• Height

  Height measurements were performed with the patient standing barefoot with the head in the Frankfort plane and the feet side by side in a medical basin with a height meter calibrated by the hospital.Then it was recorded The Blood Lipids and BMI Monitoring Form.

  1 day before the study

• Body Mass Index

  BMI was calculated by dividing body weight by the square meter of height (BMI=kg/m2). Then it was recorded The Blood Lipids and BMI Monitoring Form.

  1 day before the study

• Six-minute walk test

  It is a widely used test to assess treatment response in moderately severe heart or lung disease or to assess functional capacity, which is a determinant of mortality and morbidity in a person with a one-time measurement (in diseases such as Alzheimer's, elderly patients, MS, Parkinson's, osteoarthritis, spinal cord injury, stroke).

Study Arms (2)

Green Walk group

EXPERIMENTAL

Patients who were admitted to the Cardiology Outpatient Clinic of Y State Hospital and passed the 6MWT conducted by the cardiology physician were eligible for participation in the green walk group. Following the physician's examination at the Cardiology Outpatient Clinic, the researcher conducted face-to-face interviews with the patients in a private room. During these interviews, the patients were administered the Structured Patient Information Form, Blood Lipids and BMI Monitoring Form, the Brief IPQ, and the MIDAS, and the collected data were recorded on the respective forms. Then, the researcher provided detailed information to the patients about green walking. For the randomized MI patients, two groups were formed, and they engaged in a 50-minute green walking three days a week for 12 weeks, under the guidance of the researcher. The green walk group's walks were scheduled differently for the two subgroups.

Other: Green walking

Control group

NO INTERVENTION

Patients who were admitted to the Cardiology Outpatient Clinic of X State Hospital and passed the 6MWT conducted by the cardiology physician were enrolled in the control group. Upon their visit to the outpatient clinic, the patients in this group underwent a face-to-face interview, during which they were administered the "Structured Patient Information Form," the "Blood Lipids and BMI Monitoring Form," the "Brief-IPQ," and the "MIDAS" as pretests. . The patients in the control group continued with their routine daily activities. No specific intervention or additional measures were implemented by the investigator in this group. Furthermore, a follow-up "Blood Lipids and BMI Monitoring Form" was administered to the patients during their visit to the Cardiology Outpatient Clinic in the middle of the study (6th week). At the end of the 12-week period, the patients in the control group underwent a posttest.

Interventions

Green walking OTHER

The researcher provided detailed information to the patients about green walking. For the randomized MI patients, two groups were formed, and they engaged in a 50-minute green walking three days a week for 12 weeks, under the guidance of the researcher. The green walk group's walks were scheduled differently for the two subgroups. The first subgroup had their 50-minute walk on Monday, Wednesday, and Saturday, while the second subgroup had their walks on Tuesday, Thursday, and Sunday. This arrangement ensured a standardized time interval between green walks for both groups.
