Angioplastia coronariana primária em pacientes com mais de 80 anos / Primary coronary angioplasty in patients over 80 years of age

Introdução: É cada vez mais prevalente o número de idosos submetidos à intervenção coronariana percutânea primária (ICPp). Historicamente, essa população apresenta pior prognóstico quando comparada aos mais jovens. Nosso objetivo foi comparar as características e os desfechos clínicos em 30 dias de pacientes ≥ 80 anos aos < 80 anos submetidos à ICPp. Métodos: Estudo de coorte observacional, prospectivo, extraído do banco de dados do Instituto de Cardiologia do Rio Grande do Sul, entre 2009 e 2013. Resultados: Foram incluídos 1.970 pacientes, sendo 122 (6,2%) com idade ≥ 80 anos. Os mais idosos mostraram predomínio do sexo feminino (50% vs. 29%; p < 0,001), diabetes (34,4% vs. 23,2%; p = 0,004), classe Killip 3 ou 4 (13,1% vs. 7,4%; p = 0,02) e tempo porta-balão superior (1,4 hora [1,0-1,9 hora] vs. 1,1 hora [0,8-1,5 hora]; p < 0,001). O fluxo TIMI 3 pós não mostrou diferença entre os grupos (86% vs. 90,7%; p = 0,08), mas o Blush 3 pós foi menor (59,3% vs. 70,9%; p = 0,01) nos idosos. O sucesso angiográfico foi obtido em 92,0% vs. 95,6%; p = 0,07. Necessidade de marca-passo provisório, arritmias graves e morte súbita abortada foram mais frequentes nos pacientes ≥ 80 anos. Taxas de eventos cardiovasculares adversos maiores e óbito em 30 dias foram mais frequentes no grupo mais idoso (32,2% vs. 11,5% e 29,7% vs. 7,2%; p < 0,001). Conclusões: Nesta análise contemporânea, pacientes ≥ 80 anos submetidos à ICPp apresentaram perfil clínico e angiográfico mais grave, tempo porta-balão mais prolongado, menor Blush 3 final, com maiores taxas de complicações hospitalares e mortalidade em 30 dias, quando comparados aos pacientes mais jovens

Background: The number of elderly patients submitted to primary percutaneous coronary intervention (PCI) is increasingly prevalent. Historically, this population has a worse prognosis when compared to the younger ones. This study aimed to compare the characteristics and 30-day clinical outcomes of patients aged ≥ 80 years to those < 80 years submitted to primary PCI. Methods: Observational, prospective cohort study, extracted from the database of Instituto de Cardiologia do Rio Grande do Sul, between 2009 and 2013. Results: A total of 1,970 patients were included, of whom 122 (6.2%) were aged ≥ 80 years. The elderly showed a predominance of the female gender (50% vs. 29%; p < 0.001), diabetes (34.4% vs. 23.2%; p = 0.004), Killip class 3 or 4 (13.1% vs. 7.4%; p < 0.02), and longer door-to-balloon time (1.4 hour [1.0-1.9 hour] vs. 1.1 hour [0.8-1.5 hour]; p < 0.001). The TIMI 3 post flow did not show any difference between the groups (86% vs. 90.7%; p = 0.08), but the Blush 3 post was lower (59.3% vs. 70.9%; p = 0.01) in the elderly. Angiographic success was obtained in 92.0% vs. 95.6%; p = 0.07. Temporary pacemakers, severe arrhythmias, and aborted sudden death were more frequently observed in patients aged ≥ 80 years. The rates of major adverse cardiovascular events and death at 30 days were higher in the older group (32.2% vs. 11.5% and 29.7% vs. 7.2%; p < 0.001 ). Conclusions: In this contemporary analysis, patients aged ≥ 80 years undergoing primary PCI had a more severe clinical and angiographic profile, longer door-to-balloon time, lower final Blush 3, with higher rates of hospital complications and 30-day mortality when compared with younger patient

Estudo comparativo entre extensäo da aterosclerose coronária com os fatores de risco e as alteraçöes na artéria da retina / Comparative study of the extension of coronary arteriosclerosis with risk factors and changes in the retinal artery

PURPOSE--To identify a possible relationship of the extent of coronary artery disease, with risk factors for coronary artery disease and the retinal arteriolar changes (evaluated by fundoscopic examination). METHODS--We studied 96 patients (66 males), 36 to 72 years of age. All patients were studied by selective cinecoronaryarteriography, fundoscopic examination, as well as evaluated for the common risk factors, cigarette smoking diabetes, dislipidemia, systemic hypertension, age, alcoholism, male sex, family history and obesity. RESULTS--Male (p < 0.001) and smoking (p < 0.01) were the statistically significant associations with the extent of coronary artery disease. No significant relationship with the extent of coronary artery disease was present for the other risk factor nor for changes in retinal arteriolar branches. CONCLUSION--A relationship between extent of coronary artery disease with male sex and a cigarette smoker is occurred. No relationship with other risk factors, nor with retinal arteriolar changes were present
