Abstract Primary cardiac lymphoma is a highly rare type of malignant tumor that originates from the lymphoid tissue within the heart or pericardium. Surgical treatment is the primary method for obtaining pathological results and relieving obstructions, and chemotherapy is the main method for disease control. We present a case of a 67-year-old woman diagnosed with primary cardiac lymphoma, presenting with shortness of breath and bilateral lower extremity edema after activity.

1 Introduction Myocardial infarction (MI) is one of the most prevalent diseases globally, characterised by a high incidence of mortality and significant economic costs. Although advancements in MI treatment have enhanced survival rates following ischaemic cardiac injury, MI continues to account for over 15% of annual deaths. Cardiac remodelling after MI is a progressive process: once initiated, it leads to further deterioration of cardiac function or progresses to heart failure (HF).
