Background: Some observational studies have investigated the relationship between long-term constipation and clinical outcomes, including mortality and CVDs, in recent years. Others have proposed a separate link between a higher risk of cardiovascular death and persistent constipation.
Objective(s): The study aimed to ascertain the association between clinical characteristics, age, fiber intake, and fluid intake with constipation incidence in patients with coronary artery disease.
Methods: At Nasiriyah Heart Center, a descriptive study design was used from the 2nd of January 2023 to the 19th of March 2024. A (purposive) nonprobability sampling was conducted to select (32) coronary artery disease patients who suffered from constipation, which was observed for three consecutive days. The researcher used the constipation severity scale and Bristol Stool Scale (BSS). 
Results: The study findings show an average age of (60.18±10.57) years. (59.4%) reported a past medical history of hypertension. It was observed that most participants (37.5%) had no prior surgical procedures. Regarding fluid intake, most participants (62.5%) reported consuming less than 2500 ml of fluids daily. Likewise, when assessing fiber intake, a substantial percentage of individuals (65.6%) indicated consuming 2-3 servings of fiber-rich foods daily. (65.6%) exhibited a lack of physical activity and movement. Statin medication emerged as participants' primary type of medication (37.5%).
Conclusion: The study presented socio-demographic factors and clinical characteristics associated with old age and male gender, in addition to inadequate knowledge, lack of activity, and a healthy diet, which are related to increased symptoms of constipation among patients with coronary artery diseases.
