This study investigates the link between the Oxfordshire Community Stroke Project (OCSP) classification and mortality rates among Hispanic patients with de novo ischemic stroke.

The OCSP classification is a straightforward clinical method for anticipating the location and dimensions of infarction among patients with ischemic stroke. This system relies solely on clinical syndromes and is uncomplicated to execute. While several studies have demonstrated its effectiveness in forecasting clinical outcomes, its applicability among Hispanic patients has not been established yet.

A multicentric analytical study was carried out in Hispanic patients with de novo ischemic stroke hospitalized in three different primary stroke centers. We collected data through the clinical records and classified them according to the OCSP classification. A χ² test was carried out to establish the association between the OCSP classification and mortality.

The study involved 500 patients, with an average age of 69 ± 13 years, and 60.4% were male. According to the OCSP Classification, 36,8% were partial anterior circulation syndrome (PACS), 24% were posterior circulation syndrome (POCS), 21,6% were lacunar syndrome (LACS), and 17,6% were total anterior circulation syndrome (TACS). The overall mortality was 11%, however, it differs between each group: TACS 21,6%, PACS 12,5%, POCS 10,0%, and LACS 0,9%. The X2 test exhibits that there is a strong statistical association between the OCSP classification and mortality (X2: 77,3 and p-value < 0,001).

There is a significant disparity between the affected circulation according to the OCSP classification and the mortality of the patients. This means that the distribution of mortality in the different circulation categories is not uniform and suggests that the affected circulation may influence the probability of death among Hispanic patients. This may have important clinical implications, as health professionals could use this information for better risk assessment and decision-making in the treatment of stroke patients.
