Results of Artery Stenting in Patients with Acute Myocardial Infarction with Comorbid Hypertension

Introduction. The study of the effectiveness of treatment of acute myocardial infarction (AMI) with comorbide arterial hypertension (AH) is an actual problem of the modern cardiology. The question of the effectiveness of coronary stenting in patients with AMI and comorbide AH is insufficiently studied. Aim. To analyze the results of the effectiveness of coronary stenting in patients with AMI with comorbide AH. Material and methods. The inclusion criteria in the study were patients with Q–IM, Q–IM and comorbide hypertension, complicated by lesions of the organs of the circulatory system. The exclusion criterion was the age over 80 years, heart failure (HF) of the functional class IV, neoplasms, severe kidney and liver diseases. Angiographic examination was performed using the Siemens Axiom Artis (Germany) for 2-3 hours after hospitalization of the patients. Results and discussion. Examined patients with AMI with comorbid hypertension often experience such cardiovascular complications: heart failure of І-III NYHA functional classes – in 100 %, acute left ventricular insufficiency of І–III of classes according to the classification of T. Killip, J. Kimbal occurs in 19.0 %, arterial fibrillation in 7.6 %, ventricular extrasystoles II–V grades in Launam – in 7.0 %, ventricular fibrillation – in 3.8 %, cardiogenic shock – in 2.9 percent. One-vascular lesions of the coronary arteries (VA) was observed in 26.7 % of patients, 2-vascular – in 28.5 %, 3-vascular – in 44.8 %, subclause and occlusion – in 57,1 % of patients. Patients with comorbid hypertension were installed one stent in 86.3 % of cases; two stents – in 13.7 %. Restoration of blood flow in the anterior mishloach VA occurred in 58.1 %, the right VA – in 26.7 %, in the envelope VA – in 12.4 %. Failure to restore the coronary blood flow was observed in 2.9 % of patients. Clinical efficacy of restoring coronary flow in patients with AMI with comorbid AH according to the results of the TIMI: TIMI 1 (partial) – 0.9 %, TIMI 2 (significant) – in 20.0 %, TIMI 3 (complete, normal) – in 76.2 %, TIMI 0 (not restarted) – in 2.9 % of patients. Conclusions. 1. Сoronary blood flow in patients with AMI with comorbid AH was renewed in the front interventricular VA in 58.1 % of the patients, in the right VA – in 26.7 %, in the envelope VA – 12.4 %, failed to restore coronary blood flow in right VA – in 2.9 % of cases. 2. Reparation of coronary blood flow in patients with AMI with comorbid AH took place according to the criteria of TIMI 1 (partial) in 0.9 %, TIMI 2 (significant) – at 20.0 %, TIMI 3 (normal) – 76,2 %, TIMI 0 (did not happen) – 2.9 % of cases, which shows the effectiveness of the interventional treatment.
