Real-World Evidence

What You’ll Learn From This Review

- How tirzepatide compares to semaglutide for major cardiovascular events in obese adults without diabetes over 12 months

- Why new-onset heart failure drove the difference between the two agents, and what that means mechanistically

- What a 70,000-patient real-world cohort can and cannot tell us about head-to-head drug comparisons

- Where the evidence is solid, where it remains speculative, and what a skeptical clinician should hold loosely

**TL;DR: In a propensity-matched real-world cohort of 35,336 pairs of obese, non-diabetic adults, tirzepatide was associated with a 14% lower risk of composite major cardiovascular events compared with semaglutide at one year, driven entirely by a 21% reduction in new-onset heart failure, with no significant difference in all-cause mortality, acute coronary syndrome, or stroke.**

STUDY TYPE: Retrospective Active-Comparator New-User Cohort Study

Abstract

**Aims:** Treatment of obesity with glucagon-like peptide-1 (GLP-1) receptor agonists improves cardiovascular outcomes. Tirzepatide, a dual glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptor agonist, achieves greater weight loss than GLP-1 receptor agonists alone; however, direct real-world comparisons of clinical outcomes are limited.

**Materials and Methods:** The authors conducted a retrospective, active-comparator, new-user cohort study using the TriNetX global federated electronic health record database. Adults (18 years or older) without diabetes who initiated tirzepatide or semaglutide for the treatment of obesity between November 2023 and August 2024 were included. Patients with recent atherosclerotic events, prior heart failure, or crossovers to the comparator were excluded. The primary outcome was major cardiovascular events including all-cause death, acute coronary syndrome, stroke, or new-onset heart failure at 12 months.

**Results:** One-to-one propensity score matching yielded 35,336 pairs. Tirzepatide was associated with a lower incidence of the composite outcome compared with semaglutide (1.90% vs. 2.18%; HR 0.86; 95% CI, 0.77–0.97; p=0.01), driven by reduced new-onset heart failure (1.04% vs. 1.29%; HR 0.79; 95% CI, 0.68–0.92; p=0.002), including both HFrEF and HFpEF. No significant differences were observed in all-cause mortality, acute coronary syndrome, or stroke. Mean weight loss was greater with tirzepatide (9.8 kg vs. 8.0 kg; p<0.001). Adverse event rates were comparable, with no new safety signals.

**Conclusions:** In obese individuals without diabetes, tirzepatide was associated with a lower risk of cardiovascular events, especially incident heart failure, compared with semaglutide, with a similar safety profile.

## What the Researchers Actually Did

Katsura and colleagues constructed a retrospective cohort from the TriNetX global federated electronic health record network, which aggregates anonymized data from more than 150 million individuals across more than 150 health systems in North and South America, Europe, the Middle East, Africa, and the Asia-Pacific region. They restricted the analysis to adults 18 years or older without diabetes who newly initiated the obesity-specific branded formulations of tirzepatide (Zepbound) or semaglutide (Wegovy) between November 2023 and August 2024. This brand-name restriction was deliberate: it excluded diabetic-indication prescriptions for Ozempic and Mounjaro, limiting the cohort to those treated specifically for obesity. Patients were excluded if they had prior heart failure at any time, prior HbA1c of 6.5% or higher within the preceding year, or an atherosclerotic event within 90 days before and 30 days after the index date. Crossover between drugs during follow-up was also an exclusion criterion.

After applying these criteria, 39,384 tirzepatide initiators and 63,675 semaglutide initiators remained. One-to-one propensity score matching on a comprehensive set of demographic, comorbidity, medication, and laboratory variables reduced each group to 35,336 well-balanced pairs. A 30-day blanking period was applied at the start of follow-up to minimize delayed capture of pre-existing diagnoses in the EHR and to align with a prior [randomized trial](https://cedclinic.com/cannabis-cannabinoids-therapeutic-applications-review/) protocol. Outcomes were ascertained using ICD-10-CM codes, and time-to-event analyses used Cox proportional hazards models over 365 days of follow-up.

## Key Findings: Primary Outcomes

- **Composite primary outcome (post-PSM):** Tirzepatide was associated with a significantly lower one-year incidence of the composite endpoint of all-cause death, acute coronary syndrome, stroke, and new-onset heart failure compared with semaglutide: 1.90% vs. 2.18%; HR 0.86 (95% CI 0.77–0.97); p=0.01.

- **Absolute risk difference:** 0.28 percentage points; number needed to treat over 12 months approximately 357.

- **Pre-PSM consistency:** The unadjusted comparison showed a similar direction of effect (2.02% vs. 2.40%; HR 0.83, 95% CI 0.75–0.91; p<0.001), suggesting the signal was not introduced by the matching process.

- **Driver of the difference:** The entire composite benefit was driven by new-onset heart failure. No component other than HF reached statistical significance after matching.

## Key Findings: Secondary Outcomes and Subgroup Analyses

**Secondary outcomes (post-PSM):**

- **All-cause mortality:** 0.09% vs. 0.09%; HR 1.00 (95% CI 0.58–1.72); p=0.996. No difference.

- **Acute coronary syndrome:** 0.41% vs. 0.38%; HR 1.06 (95% CI 0.82–1.37); p=0.668. No difference.

- **Stroke (CVA and TIA combined):** 0.53% vs. 0.62%; HR 0.85 (95% CI 0.69–1.06); p=0.143. No significant difference, though a trend toward reduction was present before PSM (HR 0.77, p=0.005).

- **New-onset heart failure:** 1.04% vs. 1.29%; HR 0.79 (95% CI 0.68–0.92); p=0.002. Statistically significant.

- **HFrEF (new-onset):** 0.31% vs. 0.43%; HR 0.72 (95% CI 0.55–0.94); p=0.015.

- **HFpEF (new-onset):** 0.53% vs. 0.65%; HR 0.81 (95% CI 0.65–1.00); p=0.048. Borderline statistical significance.

- **Weight loss:** After treatment, mean body weight was 95.9 kg with tirzepatide vs. 97.7 kg with semaglutide; weight loss 9.8 kg vs. 8.0 kg (p<0.001). At 90 days the difference was only 0.3 kg, with greater separation occurring later in follow-up.

**Subgroup analyses:** The direction of effect favoring tirzepatide for the composite primary outcome was generally consistent across all prespecified subgroups, including age (18–64 years: HR 0.91, 95% CI 0.77–1.06; 65 years and older: HR 0.82, 95% CI 0.66–1.02), sex (male: HR 0.88, 95% CI 0.72–1.08; female: HR 0.86, 95% CI 0.73–1.02), BMI below 30 (HR 0.71, 95% CI 0.40–1.24) and BMI 30 or above (HR 0.76, 95% CI 0.60–0.96), and across racial groups, renal function strata, HbA1c levels, hypertension status, dyslipidemia status, ischemic heart disease status, and sleep apnea status. No subgroup showed a statistically significant interaction favoring semaglutide.

## Adverse Events and Safety Profile

After propensity score matching, the overall adverse event profile was similar between tirzepatide and semaglutide. Nausea was modestly more frequent with semaglutide (8.00% vs. 7.33%; p=0.002), as were constipation (3.33% vs. 3.02%; p=0.032) and abdominal pain (11.7% vs. 11.2%; p=0.038). Rates of vomiting, GERD, dyspepsia, diarrhea, abdominal distension, and anorexia did not differ significantly between groups. In a supplementary analysis restricted to patients who discontinued either medication within 365 days, adverse event rates remained comparable between the two groups after re-matching (9,523 pairs), suggesting that treatment-limiting adverse events occurred at similar frequencies.

## Statistical Approach and Rigor

The study employed an active-comparator new-user design, which is methodologically stronger than a naive comparison or a prevalent-user design, because it aligns the start of follow-up with treatment initiation and avoids prevalent-user bias and indication confounding from diabetic-use prescriptions. Propensity score matching on an extensive covariate set achieved standardized mean differences below 0.1 on all included variables after matching, meeting the conventional threshold for adequate balance. Cox proportional hazards models provided time-to-event estimates; Kaplan-Meier curves with log-rank tests supplemented the primary analysis. Subgroup analyses were performed with PSM repeated within each subgroup and restricted to patients with available values for the relevant variable, reducing the risk of imputing balance across strata. A 30-day blanking period mitigated reverse causation from pre-existing but uncoded diagnoses. Outcomes were ascertained from ICD-10-CM codes in a federated database, which limits direct adjudication. Missing data in laboratory variables ranged from 38% to 55% in some fields (e.g., HbA1c: 52–53% missing after PSM); continuous values after PSM reflect means among patients with available measurements, which introduces a potential source of selection bias in the laboratory-based subgroup analyses. No adjustment for multiple secondary comparisons was reported, which is relevant to the borderline HFpEF p-value of 0.048.

## Clinical Takeaway

For clinicians managing obesity in patients without diabetes, this real-world analysis provides the largest direct head-to-head cardiovascular outcome comparison to date between tirzepatide and semaglutide. The signal is specific: tirzepatide appears to reduce the incidence of new-onset heart failure, encompassing both HFrEF and HFpEF subtypes, while offering no detectable incremental benefit on atherosclerotic events or mortality at 12 months. The absolute risk difference is small (0.25 percentage points for heart failure), the follow-up is short, and this is an observational study that cannot establish causation. That said, the consistency of the heart failure signal across prespecified subgroups and HF subtypes, the biological plausibility of GIP co-agonism contributing to favorable cardiac remodeling and [anti-inflammatory effects](https://cedclinic.com/cbd-antioxidative-anti-inflammatory-properties-benefits/), and the 35,000-pair sample size all make this finding worth tracking closely as longer-term data emerge.

**Clinical Bottom Line: In propensity-matched real-world data from over 70,000 non-diabetic obese adults, tirzepatide outperformed semaglutide primarily by reducing new-onset heart failure at one year, while atherosclerotic event rates and mortality were statistically indistinguishable between the two agents.**

## Why This Matters Clinically

Heart failure, particularly HFpEF, is among the most rapidly growing cardiovascular diagnoses globally, and obesity is one of its strongest modifiable risk factors. Until now, tirzepatide’s cardiovascular outcome data have been largely derived from trials in diabetic populations or from studies that examined treatment effects in patients who already had HFpEF (the SUMMIT trial). The question of whether dual GIP/GLP-1 agonism can prevent de novo heart failure in obese individuals without diabetes had not been directly addressed in a head-to-head comparison with semaglutide at scale. This study, despite its observational design, offers the first large real-world evidence that tirzepat
