Background Acute cholecystitis (AC) presents as inflammation of the gallbladder, predominantly attributed to gallstones obstructing the cystic duct. Another notable etiology is ischemic cholecystitis, often stemming from severe illnesses that compromise blood flow to the splanchnic system. Individuals with pre-existing cardiovascular conditions or undergoing cardiopulmonary surgery encounter elevated risks of gastrointestinal pathology, leading to heightened morbidity and mortality rates. In these cases, AC stands out as a significant concern, whether it originates from gallstones or is acalculous (ischemic). Methods We conducted a single-center, retrospective cohort study at the National Medical Center in Mexico City, Mexico. We included demographic, clinical, laboratory, preoperative, intraoperative, and postoperative data. Our main objectives were to describe the characteristics of our population and identify predictors of major complications following surgery for AC in patients with heart disease. Results Our study encompassed 18 patients diagnosed with both AC and cardiac disease, with acute myocardial infarction being the leading cause of admission, constituting 38.9% of cases. The clinical presentation was characterized by right hypochondrial pain, observed in all patients, while Murphy’s sign was evident in 44.4% of cases. Additionally, various non-specific symptoms were present in varying percentages across the patient cohort. Concerning imaging studies, 88% of our cohort underwent ultrasound (USG), while computed tomography (CT) was utilized in 55% of patients. Among those who had USG, the most prevalent findings were gallbladder wall thickening in 56% and perivesicular fluid in 37.5%. In patients who underwent CT scans, the predominant observations included perivesicular fluid in 66% and perivesicular fat stranding in 55%. In terms of intraoperative findings, gallbladder empyema and necrosis were the most common findings identified in 55.6% of the cases. After surgery, 61.1% had no complications or developed mild complications, while 11.1% experienced moderate to severe complications without resulting in death; the mortality rate was 27.8% in our cohort. Overall, major complications or death were present in 38.9% of our cohort. In the postoperative data analysis, the use of mechanical ventilation and vasopressors showed a significant correlation with increased morbidity and mortality. Conclusions Our study contributes valuable information to the international literature, providing insights into the complications faced by the Mexican population in the context of heart diseases, particularly among patients suffering from cholecystitis. Within individuals with cardiac disease, the occurrence of AC requiring surgical intervention is associated with heightened morbidity and mortality rates, with our cohort experiencing rates as high as 38.9%. Consistent with findings in the international literature, these results underscore the critical importance of continuing the search for novel clinical or laboratory predictors for this high-risk population. While most parameters assessed in this study did not show any correlation with major complications, exceptions were observed in postoperative vasopressors and mechanical ventilation.
