Kliničke, angiografske i terapijske specifičnosti akutnog infarkta miokarda sa ST elevacijom kod osoba starijih od 75 godina

Abstract

Uvod: Pacijenti sa akutnim infarktom miokarda sa ST elevacijom treba da budu podvrgnuti reperfuzionoj terapiji, pre svega pPCI, bez obzira na životnu dob, ali zbog veće učestalosti komorbiditeta, faktora rizika za koronarnu bolest i višesudovne koronarne bolesti, kod pacijenata starije životne dobi, odluka o reperfuzionoj terapiji treba da se donese sa dobrom procenom odnosa rizik – benefit. Cilj: Utvrđene su razlike u kliničkoj slici, angiografskom nalazu, terapijskom pristupu, toku i ishodu akutnog infarkta miokarda sa ST elevacijom u starih osoba u odnosu na mlađu životnu dob (mlađi od 75 godina). Materijal i metode: U studiju je uključeno 240 pacijenata sa akutnim infarktom miokarda sa ST elevacijom, podeljeni u dve komparabilne grupe (120 bolesnika starijih i kontrolna grupa 120 mlađih od 75 godina), koji su izabrani metodom slučajnog izbora, po redosledu prijema u bolnicu. Za pacijente iz obe grupe popunjavan je upitnik, a tretirani su po jedinstvenom protokolu lečenja. Rezultati: U ispitivanom uzorku, u grupi bolesnika starijih od 75 godina reperfuziona terapija je bila primenjena u 85% slučajeva. Intrahospitalni mortalitet za ceo uzorak je 11,7% i u skladu je sa drugim istraživanjima [27]. Mortalitet u grupi pacijenata preko 75 godina je bio 12,5%, a u grupi pacijenata sa manje od 75 godina 10,8% (p=ns). Zaključak: Klinička slika bolesti kod bolesnika starije životne dobi je češće atipična što korelira sa drugim studijama [31, 35], a tok bolesti komplikovaniji i ishod lošiji. Kod bolesnika starijih od 75 godina češća je višesudovna koronarna bolest. Primarna perkutana koronarna intervencija u akutnom infarktu miokarda sa ST elevacijom u pacijenata starije životne dobi potvrđuje benefit u lečenju, toku i ishodu bolesti.

Introduction: Patients with ST segment acute myocardial infarction should undergo reperfusion therapy, PCI in the first place, no matter their life age. However, due to high frequency of comorbidities, risk factors for coronary disease and multi-vessel coronary disease, the decision of reperfusion therapy in elderly patients should be made according to the good evaluation or risk benefit ratio. Aim: The differences have been determined in the clinical picture, angiographic finding, therapeutic approach, course and outcome of ST segment acute myocardial infarction in elderly patients in relation to younger life age (less than 75 years). Material and methods: The study included 240 patients with ST segment acute myocardial infarction. They were randomly divided into two comparable groups according to the date of their hospitalization (120 patients older than 75 and control group of 120 patients younger than 75 years). Both groups of patients filled out the survey and were treated according to the same protocol. Results: In the examined sample of the group of patients older than 75 the reperfusion therapy was performed in 85% of cases. Intrahospital mortality for the entire sample was 11.7% and is in coherence with other researches [27]. Mortality in the group of patients older than 75 years was 12.5%, and it was 10.8% (p=ns) in the group of patients younger than 75. Conclusion: Clinical picture of disease in elderly patients is atypical thus correlating with other studies [31, 35], and course of illness more complicated and with a worse outcome. Multi-vessel disease is more common in patients older than 75 years. Primary percutaneous coronary intervention in STEMI in elderly patients confirms benefits in treatment, course and outcome of disease.
