The RESINCCRO registry analyzed 3,029 Mexican adults with chronic coronary syndrome and found high rates of cardiometabolic conditions including obesity (76%), hypertension (69%), and diabetes (44%). Despite widespread use of cholesterol-lowering medications (93% on statins), only 26% achieved target LDL cholesterol levels below 55 mg/dL, and cardiac rehabilitation participation was very low at 6.2%. The study revealed that 60% of patients had obstructive coronary artery disease and nearly a quarter experienced persistent angina symptoms.
Why it matters
This registry identifies critical gaps in chronic coronary syndrome management in Mexico, particularly in achieving cholesterol goals and cardiac rehabilitation access, which are key components of preventing heart attacks and death. The findings suggest opportunities to improve secondary prevention strategies in Latin American populations that may have different clinical characteristics than those in high-income countries where most cardiovascular guidelines originate.

BACKGROUND: Chronic coronary syndromes (CCS) remain under-characterized in Latin America, where clinical profiles may differ from high-income countries. OBJECTIVE: We aim to characterize the clinical presentation, coronary anatomic profile, and pharmacologic treatment patterns of adults living with CCS using data from the Mexican Chronic Coronary Syndrome Registry (RESINCCRO). METHODS: RESINCCRO is an observational, multicenter, cross-sectional registry conducted across ~50 centers in five regions from Mexico. We included adults ([≥]18 years) enrolled between September 2024 and March 2025 who met 2019 ESC CCS criteria. Coronary imaging data was collected from medical records into a standardized electronic case report form. RESULTS: We enrolled 3,029 adults (men [72.5%]; mean age 67.2 {+/-} 10.7 years). Cardiometabolic comorbidities were frequent: overweight/obesity (76%), arterial hypertension (69.0%), type 2 diabetes (44.0%), and chronic kidney disease (24.2%). Persistent angina/equivalents occurred in (23.9%), of which most had Canadian Cardiovascular Society class I – II (91.2%). The mean LVEF was of 53.7 {+/-} 12.0. Cardiac rehabilitation participation was (6.2%). Median LDL-C was 70 mg/dL (IQR 51 – 95) and LDL <55 mg/dL was only 26.1%, despite high prescription of lipid-lowering therapies, including statins (93.2%), ezetimibe (24.6%), and PCSK9 inhibitors (2.4%). 60.3% had obstructive epicardial disease. CONCLUSIONS: Mexican adults with CCS exhibit high cardiometabolic burden, frequent symptoms, suboptimal LDL-C goal attainment, low rehabilitation uptake, and a substantial obstructive phenotype. These findings highlight opportunities to intensify secondary prevention, adopt mechanism-directed evaluation and therapy, and expand cardiac rehabilitation to improve CCS care in Mexico.
