Early or partial results. Treat as a signal, not a conclusion.
This is a narrative review applying the exposome framework to environmental cardiovascular risk factors in Dire Dawa, Ethiopia, documenting moderate-to-high levels of air pollution, noise, and thermal extremes, but identifying critical gaps in prospective data and intervention evidence. The analysis relies on observational and modeled data rather than primary clinical trials or validated cohort studies, and no causal link to cardiovascular outcomes in this population has been empirically established.
Narrative review. Dire Dawa, Ethiopia; a rapidly urbanizing secondary city. No specific clinical cohort or patient population enrolled.. Dire Dawa, Ethiopia.
PM2.5 often exceeds WHO guidelines, with episodic peaks reaching 154 μg/m³ Noise levels in commercial zones (81.97 dBA) and residential zones (68.08 dBA) surpass Ethiopian standards Daytime temperatures regularly exceed 33 °C, with projected warming of 1.0–1.5 °C per 25 years under RCP8.5
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians and public health authorities in Dire Dawa should recognize substantial but poorly characterized environmental cardiovascular risk; however, without prospective cohort data or trial evidence, the magnitude of attributable cardiovascular disease burden and efficacy of interventions remain uncertain. The review prioritizes research gaps and policy recommendations over actionable clinical guidance.

The 2026 European Society of Cardiology (ESC) clinical consensus statement identifies air pollution, noise, extreme heat, and chemical exposures as major cardiovascular risk factors. However, evidence from rapidly urbanizing African cities remains scarce. Purpose: This review applies the exposome framework to Dire Dawa, Ethiopia, synthesizing available data on environmental cardiovascular risk factors and outlining public health imperatives for clinical practice and policy. A narrative review of peer-reviewed literature, satellite-derived data, modeled forecasts, and gray literature was conducted, focusing on air quality, noise, thermal extremes, and chemical exposures. Dire Dawa exhibits moderate-to-high levels of multiple environmental hazards. PM2.5 often exceeds WHO guidelines, with episodic peaks reaching 154 μg/m³. Noise levels in commercial (81.97 dBA) and residential (68.08 dBA) zones surpass Ethiopian standards. Daytime temperatures regularly exceed 33 °C, with projected warming of 1.0–1.5 °C per 25 years under RCP8.5. Heavy metal exposure from e waste is suspected but unquantified. These exposures converge on oxidative stress, inflammation, endothelial dysfunction, autonomic imbalance, and circadian disruption—pathways that promote hypertension, myocardial infarction, and stroke. Dire Dawa’s environmental cardiovascular risk is substantial but poorly characterized. Critical gaps include the absence of continuous monitoring, prospective cohorts, and intervention trials. The Ethiopian Ministry of Health should embed environmental screening into hypertension programmes; the ESC should provide low resource implementation guidance; international funders should prioritize exposome CVD research in African secondary cities.
