[Cardiogenic shock in myocardial infarct]

Area of Science:

• Cardiology
• Internal Medicine
• Public Health

Background:

• Myocardial infarction (MI) remains a leading cause of mortality worldwide.
• Cardiogenic shock (CS) is a severe complication of MI with high fatality rates.
• Understanding trends in MI and CS incidence and outcomes is vital for public health strategies.

Purpose of the Study:

• To analyze the incidence, clinical characteristics, and outcomes of patients with myocardial infarction.
• To specifically investigate the trends and lethality of cardiogenic shock in myocardial infarction patients.
• To identify associated risk factors and clinical presentations of cardiogenic shock in MI.

Main Methods:

• Retrospective analysis of 1605 patients admitted with myocardial infarction over a 24-year period.
• Data collection included patient demographics, clinical presentation, MI localization, and comorbidities.
• Analysis of incidence, mortality, and risk factors for cardiogenic shock in MI patients.

Main Results:

• Overall MI mortality was 26.5%. Cardiogenic shock occurred in 10.3% of MI patients, with a high lethality of 85%.
• Over 5 years, CS incidence decreased from 14.4% to 5.3%, but lethality increased from 75.5% to 91.4%.
• Common presentations included angina pectoris (80%), asthmatic (49%) and irradiating pain (41%). Hypertension (21.7%), diabetes (15%), and rhythm disorders (32.2%) were notable comorbidities.

Conclusions:

• Despite a decrease in incidence, cardiogenic shock in myocardial infarction presents a growing challenge due to increased lethality.
• The study highlights the critical need for improved management strategies for cardiogenic shock in MI patients.
• Further research into risk stratification and early intervention for high-risk MI patients is warranted.
