Patient Demographics Summary

Age: 72 | Marital Status: Married | Occupation: Retiree | Informant (Relationship to Patient): Reliable | Onset Season: Guyu (Grain Rain) | Chief Complaint (Reported by Proxy): Cough and expectoration accompanied by chest tightness and shortness of breath for 1 week. | History of Present Illness: One week prior to admission, the patient developed a cough and began expectorating sputum; the sputum was white in color and thick in consistency. These symptoms were accompanied by chest tightness and shortness of breath, as well as occasional chest pain. The patient denied experiencing altered consciousness, urinary frequency, urgency, or dysuria, hemoptysis, abdominal distension or pain, or skin rashes. As symptoms showed no significant improvement, the patient presented to our hospital's Emergency Department. Laboratory blood tests performed in the ED indicated: D-dimer 6.43 mg/L, Troponin T 26.4 pg/mL, and Lactate Dehydrogenase (LDH) 441 U/L. A non-contrast chest CT scan (performed on 2026-05-03 at 13:59) revealed: 1. Bilateral pulmonary inflammation; post-surgical changes consistent with a left lower lobe lobectomy. 2. Mild cardiomegaly (correlation with clinical findings recommended). 3. A small amount of pleural effusion in the left thoracic cavity. To facilitate further systematic diagnosis and treatment, the Emergency Department recommended admission with a preliminary diagnosis of "Community-Acquired Pneumonia (Non-Severe)." | Findings on Admission: Cough and expectoration (sputum is white and viscous); mild chest tightness and shortness of breath (not significantly exacerbated by physical activity); no hemoptysis; occasional chest pain; low-grade fever (no high-grade fever); dry mouth; no nasal congestion or rhinorrhea; no palpitations; no nausea or vomiting; no abdominal distension or pain. Appetite is fair; sleep quality is adequate; bowel movements and urination are normal. No significant weight loss has been noted recently. | Past Medical History: Generally in fair health.

Upon admission, relevant examinations were completed: CTPA indicated interstitial pneumonia in both lungs; no pulmonary embolism was observed.
