Tirzepatide exposure does not significantly increase or decrease the risk of adverse cardiovascular events (myocardial infarction, coronary artery disease, heart failure, stroke) or adverse renal events (urinary tract infections, kidney stones, renal impairment, renal cell carcinoma) in participants with type 2 diabetes or obesity compared to control groups.

For patients with T2DM or obesity, current evidence from multiple randomized trials indicates that tirzepatide does not significantly increase or decrease the risk of major cardiovascular events (like heart attack or stroke) or specific renal adverse events (like kidney stones or UTIs) compared to other treatments or placebo. While long-term safety in high-risk groups requires more data, short-to-medium term use appears safe regarding these specific outcomes.

GoodRefutesHIGH confidence
Overall, no significant relation was observed between tirzepatide exposure and adverse cardiovascular events (RR = 0.83, 95%CI: 0.63–1.08, p = 0.16, I²=0%) or adverse renal events (RR = 1.22, 95%CI: 0.78–1.89, p = 0.39, I²=0%) compared with the control group.

Why this rating

Meta-analysis of 20 RCTs with 15,905 participants provides high statistical power, though follow-up durations were noted as short.
