Brief Summary

The purpose of this study is the investigation of the effect of nurse-led nutritional education of post-CABG patients on their dietary pattern, on their adherence to it, but also on their quality of life and well-being.

Conditions

Coronary Heart Disease

Keywords

Coronary Artery Bypass Grafting; Nutritional Education from nurses; Weight measurement; adherence to the Mediterranean diet

Outcome Measures

Primary Outcomes (1)

• Improving dietary choices and habits of patients with Coronary Heart Disease who underwent coronary artery bypass surgery

  Through nutritional education and discussion with the researcher, the goal is for patients to understand healthy eating choices, make better choices regarding their diet, and improve the outcome of surgery.

  6 months from the first meeting

Secondary Outcomes (4)

• Improvement in body weight (kg) of patients

  Until 6 months from the first meeting with the researcher

• Improving patients' Body Mass Index to healthy limits

  6 months from the first meeting

• improvement of patients' body fat percentage (%) and body water percentage (%)

  Until 6 months from the first meeting

• Improving patients' chest, waist and hip circumferences (cm) to healthy limits

  Until 6 months from the first meeting

Study Arms (2)

Group A (Control Group)

ACTIVE COMPARATOR

These are patients who will have their body measurements, weight, body fat and water percentage measured. They will also complete the questionnaires that will be included in the study, but they will not receive any nutritional education from the researcher.

Behavioral: Patients of Group A and B both are filling out the questionnaire "Mediterranean diet questionnaire (MEDAS)"; Behavioral: Patients of Group A and B both are filling out the "Mini Nutritional Asessment" questionnaire; Behavioral: Patients of Group A and B both are filling out "Nottingham Health Profile Scale" questionnaire; Behavioral: Patients of Group A and B both are filling out the "Cardiovascular Diet Questionnaire-2"; Other: Measurement of patient somatometric characteristics

Intervention Group (Group B)

ACTIVE COMPARATOR

These are patients who will have their body measurements, weight, body fat and water percentage measured. They will also complete the questionnaires that will be included in the study. These patients will receive nutritional education from the researcher, through an information sheet, phone calls and messages. The goal is to improve their measurements and their nutritional choices due to this education, compared to the patients in Group A.

Behavioral: Patients of Group A and B both are filling out the questionnaire "Mediterranean diet questionnaire (MEDAS)"; Behavioral: Patients of Group A and B both are filling out the "Mini Nutritional Asessment" questionnaire; Behavioral: Patients of Group A and B both are filling out "Nottingham Health Profile Scale" questionnaire; Behavioral: Patients of Group A and B both are filling out the "Cardiovascular Diet Questionnaire-2"; Other: Measurement of patient somatometric characteristics; Behavioral: Nutritional education and discussion with group B patients

Interventions

Patients of Group A and B both are filling out the questionnaire "Mediterranean diet questionnaire (MEDAS)" BEHAVIORAL

This questionnaire will be completed by patients in both groups. The aim of this questionnaire is to assess the patients' dietary choices and how beneficial they are for their health, according to the Mediterranean diet model.

Group A (Control Group); Intervention Group (Group B)

Patients of Group A and B both are filling out the "Mini Nutritional Asessment" questionnaire BEHAVIORAL

This questionnaire will be completed by patients in both groups. The aim of this questionnaire is to assess the nutritional status of the patients, their level of nutrition and appetite for food, and the potential risk of malnutrition.

Group A (Control Group); Intervention Group (Group B)

Patients of Group A and B both are filling out "Nottingham Health Profile Scale" questionnaire BEHAVIORAL

This questionnaire will be completed by patients in both groups. The aim of this questionnaire is to assess the subjective discomfort of the individual with health problems as well as the extent to which these problems affect their normal activities.

Group A (Control Group); Intervention Group (Group B)

Patients of Group A and B both are filling out the "Cardiovascular Diet Questionnaire-2" BEHAVIORAL

This questionnaire will be completed by patients in both groups. The aim of this questionnaire is to assess the dietary choices of patients with cardiovascular diseases, such as the patients in this study.

Group A (Control Group); Intervention Group (Group B)

Measurement of patient somatometric characteristics OTHER

Measurement of body weight, Body Mass Index, Fat and Water Percentage, Chest, Waist and Hip Circumference of patients using a tape measure and electronic scale-lipometer. Also, measurement of bloodless blood pressure and fasting glucose.

Group A (Control Group); Intervention Group (Group B)

Nutritional education and discussion with group B patients BEHAVIORAL

Nutritional education using an information leaflet, e-mails and telephone calls to patients in group B only. Discussion regarding their dietary choices before surgery, identification of wrong habits and efforts to improve them afterwards. It will concern all the basic categories of healthy eating (preference for fruits, vegetables, proteins, healthy carbohydrates, reduction of saturated fat, salt and sugar and information about nutritional labels and how to choose foods according to them). The goal is for patients who will receive this education to improve their measurements in repeat meetings with the researcher, compared to those who will not be informed.

Intervention Group (Group B)
