Insights
Acute myocardial infarction (AMI) in men is linked to higher plasma viscosity and fibrinogen, and lower albumin, globulin, red blood cell counts, and hematocrit. These hemorheological changes occur regardless of ST-segment elevation.
Area of Science:
- Cardiovascular Medicine
- Hematology
- Biophysics
Background:
- Acute myocardial infarction (AMI) is a critical cardiovascular event.
- Hemorheological parameters play a role in cardiovascular disease pathophysiology.
- Understanding hemorheological changes in AMI is crucial for patient management.
Purpose of the Study:
- To compare hemorheological parameters in male patients with AMI versus controls.
- To investigate differences in hemorheological parameters based on ST-segment elevation in AMI.
- To identify key hemorheological alterations associated with AMI.
Main Methods:
- Compared plasma viscosity, protein concentrations (albumin, globulin, fibrinogen), blood cell counts (red and white), hemoglobin, and hematocrit.
- Included 42 male patients with AMI (22 with STEMI, 20 without STEMI) and 20 healthy controls.
- Utilized standard laboratory assays for hemorheological and biochemical analyses.
Main Results:
- Significantly higher plasma viscosity in AMI patients compared to controls (P = .012 and P = .046).
- Elevated fibrinogen concentrations and decreased albumin and globulin levels in AMI patients.
- Reduced red blood cell counts and hematocrit in AMI patients compared to controls (P = .0001 and P = .014).
Conclusions:
- AMI in males is associated with increased plasma viscosity and fibrinogen.
- Decreased albumin, globulin, red blood cell count, and hematocrit are observed in male AMI patients.
- These hemorheological changes are consistent regardless of ST-segment elevation in AMI.
Abstract:
We compared hemorheological parameters in 42 male patients with acute myocardial infarction (AMI), with (n = 22) or without (n = 20) ST-segment elevation and in 20 controls. Plasma and blood viscosity (cP), plasma protein (g/dL) and fibrinogen (mg/dL) concentrations, red (10(6)/µL) and white (10(3)/µL) blood cell counts, hemoglobin concentration (g/dL), and hematocrit (%) were compared. Plasma viscosity was significantly higher in patients with AMI with (P = .012) and without (P = .046) ST-segment elevation than in controls. Patients with AMI with and without ST-segment elevation had significantly lower albumin (P = .002 and P = .009) and globulin (P = .001 and P = .007) concentrations, red blood cell counts (P = .0001 and P = .004), and hematocrit (P = .014 and P = .040) and significantly higher fibrinogen concentrations (P = .0001 and P = .001) than controls. These findings suggest that AMI in males is associated with increased plasma viscosity and fibrinogen concentrations and with decreased albumin and globulin concentrations, erythrocyte count, and hematocrit, regardless of ST-segment elevation.
