Final answer:
The patient's development of heart failure is most likely contributed by hypertension, diabetes mellitus, and ischemic heart disease.
Step-by-step explanation:
The factors in the patient's history that most likely contributed to their development of heart failure are:
- Hypertension: High blood pressure forces the heart to pump harder, putting more strain on it.
- Diabetes mellitus: Diabetes can cause changes in the body, such as high cholesterol levels, which are risk factors for cardiovascular disease.
- Ischemic heart disease: This refers to a reduced blood supply to the heart, which can lead to heart failure.
