Magnesium status in patients with acute myocardial infarction: a pilot study

Area of Science:

• Cardiology
• Biochemistry
• Clinical Medicine

Background:

• Magnesium plays a crucial role in cardiovascular function.
• Magnesium deficiency is suspected in acute myocardial infarction (AMI) patients.
• Diagnostic tools for assessing magnesium status require validation.

Purpose of the Study:

• To evaluate the efficacy of the magnesium retention test (MRT) in identifying magnesium deficiency in AMI patients.
• To compare muscle magnesium levels between AMI patients and healthy controls.
• To explore the relationship between magnesium status and AMI.

Main Methods:

• A pilot study involving 5 male patients with AMI and 6 healthy male controls (aged 35-65).
• Administration of a magnesium load followed by a magnesium retention test (MRT).
• Muscle quadriceps lateralis biopsy for direct magnesium content analysis.

Main Results:

• Magnesium retention was significantly higher in the AMI group (42%) compared to the control group (22%) (p < 0.01).
• Muscle biopsy confirmed lower magnesium content in AMI patients, validating the MRT findings.
• A prolonged bleeding time was observed after the magnesium load in AMI patients.

Conclusions:

• The magnesium retention test (MRT) effectively identifies magnesium deficiency in acute myocardial infarction patients.
• AMI patients exhibit lower muscle magnesium levels, suggesting a significant role for magnesium in the condition.
• Further research is warranted to explore the therapeutic implications of magnesium supplementation in AMI.
