Objetivo: describir las características clínicas y paraclínicas de los pacientes con coronariografía normal o sin lesiones significativas. Diseño: descriptivo, retrospectivo. Metodología: se revisaron las historias clínicas y se registraron los hallazgos demogr áficos y clínicos, el perfil lipídico, el electrocardiograma, la ecocardiografía, la prueba de esfuerzo, la coronariografía y las complicaciones de esta última. Resultados: el 9.5% (167/1.752) de las coronariografías realizadas por sospecha de enfermedad coronaria fueron normales. El 60.5% ocurrieron en mujeres. El 50% de los hombres tuvo dolor precordial típico, en el 53.5% de las mujeres fue atípico. El 73% eran hipertensos y el 7.2%, hipotiroideos. Hubo angina inestable en 61.7%, infarto agudo de miocardio en 22.8% y probable síndrome X cardiovascular en 28.8%. El nivel de triglicéridos fue más bajo en los pacientes con infarto (p
Patients with depression, congestive heart failure, hypertension, or seizures were excluded. Patients were stratified into adherent and non-adherent groups based on a proportion of days covered greater than 0.80 in the year after OMPM initiation. The analysis followed 'intent-to-treat' design, with 1-year follow-up concurrent with adherence assessment. HRU and costs (2017 USD) during the 12 months follow-up were compared in 1:1 propensity score-matched adherent and non-adherent samples. Results: Data for 1,733 matched pairs were analyzed. The likelihood of an emergency room (ER) visit was somewhat lower for the adherent versus nonadherent groups in the overall population [relative risk (RR) of 0.89, 95% confidence interval (CI) 0.80, 1.00] but was significantly lower for adherent patients among antidepressant users (RR=0.78, 95% CI, 0.67,0.91). Adherence among antihypertensive users was associated with lower risk of hospitalization (RR of 0.48, 95% CI, 0.26, 0.89) and fewer ER visits (mean 0.56 vs. 0.38, p=0.05). Among non-adherent antihypertensive users, inpatient and overall costs were $1,138 and $797 higher, respectively, although differences were not statistically significant. Migraine/headache-related costs represented approximately 30% of the inpatient cost differential. Conclusions: Migraine patients who are adherent to OMPMs may have reduced ER and inpatient utilization, as well as decreased costs, although these associations may depend on the type of OMPM used. Further investigation is warranted to understand how OMPM adherence affects healthcare utilization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
