Abstract Background Cardiovascular diseases (CVDs) are the most common cause of morbidity and mortality among patients with type 2 diabetes mellitus (T2DM). There is a paucity of data on the pattern of first manifestation of CVD and the outcome among patients with T2DM in Cameroon. Objectives We aimed to examine the pattern of the first manifestation of CVD and the outcome among patients with T2DM. Methods Between January 2017 and December 2023, files of patients with T2DM hospitalized for the first observed CVD were reviewed. We identified cases of three incident overt clinically manifest CVD complications (acute myocardial infarction [AMI], stroke, and heart failure) in hospitalized T2DM patients. Patients with a previous history of CVD were excluded. Results Out of the 1091 patients hospitalized with T2DM, we identified 261(23.9%) patients with clinically overt CVD, of whom 129 (49.4%) were females. The mean age was 63.9 ± 12.1 years and ranged from 15 to 91 years. Women were significantly older compared to men (65.4 ± 11.4 years vs. 62.5 ± 12.6 years; p = 0.042). Hypertension was reported in 201 (77%; 95% CI: 71.4–82) patients. Any form of chronic kidney disease was seen in 15 (5.8%; 95% CI: 3.3–9.3) patients. HIV infection was seen in 5 (1.9%; 95% CI: 0.6–4.4) patients. Stroke was the most common incident clinically overt CVD in 144 (55.2%; 95% CI: 48.9–61.3) patients, followed by heart failure in 105 (40.2%; 95% CI: 34.2–46.5) patients, and Acute MI in 12 (4.6%; 95% CI: 2.4–7.9) patients. The mean length of hospital stay was 9.7 ± 6.6 days. Patients with stroke had a significantly longer hospital stay > 7 days (63% vs. 48.7%, p = 0.021). The in-hospital case fatality was seen in 35 (13.4%; 95% CI: 9.5–18.2) patients. Conclusion Nearly 1 out of 4 hospitalized patients with T2DM was hospitalized for a first CVD. Stroke and heart failure are the most common initial manifestations of CVD. More than three-quarters of the patients had concomitant hypertension and the in-hospital case fatality was high. Clinical trial number Not applicable.
