Recurrent myocardial infarctions secondary to luetic coronary arteritis in hypertrophic cardiomyopathy. A case report
Insights
A patient with hypertrophic cardiomyopathy experienced two myocardial infarctions (MIs) due to syphilitic coronary arteritis. This rare condition caused aneurysmal coronary arteries without obstruction, leading to thrombus formation and MIs.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Investigating the link between syphilitic infection and cardiovascular events.
- Understanding the presentation of hypertrophic cardiomyopathy (HCM) in the context of atypical coronary artery disease.
Observation:
- A 43-year-old man with no traditional risk factors presented with recurrent acute myocardial infarctions (MIs).
- Positive serological tests indicated a past syphilitic infection.
- Cardiac imaging revealed hypertrophic cardiomyopathy (HCM) and diffusely aneurysmal coronary arteries without obstructive lesions.
Findings:
- Syphilitic coronary arteritis was postulated as the cause of aneurysmal coronary arteries and subsequent thrombus formation.
- Endomyocardial biopsy did not show characteristic HCM histology, despite clinical and angiographic evidence.
- The findings suggest a rare presentation of syphilis-induced vasculitis leading to acute coronary events.
Implications:
- Highlights the importance of considering syphilitic coronary arteritis in patients with unexplained coronary artery aneurysms and MIs.
- Suggests that syphilitic arteritis can manifest without typical ostial stenosis.
- Underscores the complex interplay between infectious diseases, cardiomyopathies, and coronary artery pathology.
Abstract:
A 43-year-old coloured man had no risk factors for atheromatous coronary artery disease but suffered two acute myocardial infarctions (MIs) in rapid succession. Serological reactions for previous syphilitic (luetic) infection were positive. Hypertrophic cardiomyopathy (HCM) without obstruction was verified, although right ventricular endomyocardial biopsy specimens did not demonstrate histological features of this disease. Extensive MI was verified on left ventricular cine angiography. Selective coronary arteriography showed that the coronary arterial tree was diffusely aneurysmal in the absence of any obstruction. We postulate that syphilitic coronary arteritis, in the absence of the more pathognomonic coronary ostial stenotic lesions, was present and may have predisposed to coronary thrombus formation and repeated acute MI. Recurrent coronary vasospasm, associated with the HCM, cannot be excluded with certainty.
