Adherence to Secondary Prevention and Influential Factors in Individuals with Coronary Angioplasty.

The study measured patients once, about three to four months after discharge, so it cannot show what happens later or whether adherence changed over time. Adherence was based on patients' reported answers collected by telephone, not on medication records or direct observation. The sample came from one clinic in Medellín and was mostly male and low income, so it may not apply to other patients. The study cannot show that treatment-related factors caused higher adherence; it only found correlations. The authors note the high adherence score did not match other studies, possibly because of timing and sociodemographic differences. Six patients in the original database had died, and the sample was completed by continuing calls, which may affect representativeness.

The article reports no aid or funding.

Do not conclude that nurse-led education or attention to these factors improved adherence. The study observed patients once and only reported associations; it did not test an intervention.
