Insights
Active Helicobacter pylori infection, identified by H. pylori stool antigen (HpSA), is linked to acute coronary heart disease (CHD). This suggests H. pylori may trigger cardiovascular events.
Area of Science:
- Cardiology
- Infectious Diseases
- Gastroenterology
Background:
- Helicobacter pylori (H. pylori) infection is a common cause of gastritis and peptic ulcers.
- The potential link between H. pylori infection and cardiovascular diseases is an area of ongoing research.
- Acute coronary heart disease (CHD) represents a significant global health burden.
Purpose of the Study:
- To investigate the association between active H. pylori infection and the occurrence of acute coronary heart disease (CHD).
- To determine if H. pylori infection acts as a trigger factor for acute cardiovascular events.
Main Methods:
- A study involving 40 patients with acute coronary syndromes and two control groups (40 patients with non-H. pylori infections and 40 healthy subjects).
- Participants were pair-matched for age, sex, and CHD risk factors.
- H. pylori stool antigen (HpSA) and serum anti-CagA were tested in all participants.
Main Results:
- A significantly higher prevalence of HpSA positivity was observed in patients with acute CHD (28/40) compared to control group A (14/40) and control group B (16/40) (p=0.00095).
- No significant difference in anti-CagA positivity was found between the CHD group and control groups.
- Concomitant positivity for HpSA and anti-CagA was significantly higher in patients with acute CHD (13/40) compared to controls (p=0.017).
Conclusions:
- The findings indicate a higher rate of active H. pylori infection in patients experiencing acute CHD.
- A significant association between HpSA and anti-CagA positivity in acute CHD patients suggests a potential role for H. pylori.
- Active H. pylori infection may serve as a trigger factor for acute cardiovascular events.
Objectives:
To evaluate the possible role of the active Helicobacter pylori infection as a trigger factor in acute coronary heart disease (CHD).
Methods:
Forty patients with acute coronary syndromes, 40 patients with infections other than H. pylori (control group A) and 40 healthy subjects (control group B), pair matched for age, sex and CHD risk factors were studied. In each patient and control subject the presence of H. pylori stool antigen (HpsA) and serum anti-CagA were tested.
Results:
Twenty-eight of patients with CHD resulted positive for HpSA compared to 14 patients of control group A and 16 subjects of group B (p=0.00095). No significant difference was found in the anti-CagA positivity among patients with CHD and control groups. Concomitant positivity for anti-CagA and HpSA was found in 13 patients with CHD, four controls of group A and five controls of group B (p=0.017)
Conclusions:
Our findings revealed a higher rate of HpSA positivity and a significantly higher association between HpSA and anti-CagA positivity in patients with acute CHD compared to control groups. These data suggest that active H. pylori infection may play a role as a trigger factor in acute cardiovascular events.
