What is the diagnosis for a patient with an electrocardiogram (EKG) showing sinus rhythm, incomplete right bundle branch block (RBBB) and left anterior fascicular block (LAFB), abnormal e-wave progression, early transition left ventricular hypertrophy, and ST elevation concerning for inferior injury, with mildly elevated troponin levels, normal complete blood count (CBC), impaired renal function with a bun/creatinine ratio indicating dehydration, and urinalysis indicating a urinary tract infection (UTI) with leukocytes, white blood cells (WBC), red blood cells (RBC), and bacteria present?

From the Research

The primary concern in this patient appears to be a urinary tract infection rather than an acute cardiac event, and treatment should include empiric antibiotics and increased fluid intake to address dehydration. The EKG findings suggest an incomplete right bundle branch block (RBBB) and left anterior fascicular block (LAFB) with ST elevation concerning for inferior injury. However, the troponin levels are low and decreasing (0.05 to 0.04), indicating minimal cardiac damage 1. The chemistry panel shows a low CO2 of 18 and elevated BUN/creatinine ratio of 26.7, suggesting possible dehydration. The urinalysis reveals signs of urinary tract infection with moderate leukocyte esterase, >50 WBCs, 6-10 RBCs, and moderate bacteria. Some key points to consider in the management of this patient include:

  • The use of aspirin in patients with cardiovascular disease, as studied in 1, which found no significant difference in cardiovascular events or major bleeding between patients assigned to 81 mg and those assigned to 325 mg of aspirin daily.
  • The importance of addressing the urinary tract infection, as it is the primary concern in this patient.
  • The need for cardiology consultation to evaluate the EKG abnormalities, particularly the ST elevation and left ventricular hypertrophy, which may represent chronic cardiac issues requiring further assessment.
  • The potential benefits of aspirin combination treatment in the treatment of coronary heart disease, as discussed in 2, which found that aspirin in combination with other drugs had higher clinical efficacy and safety, and could significantly reduce the level of inflammatory factors in CHD patients. Given the patient's presentation and the evidence available, treatment with empiric antibiotics such as nitrofurantoin 100mg twice daily for 5-7 days or trimethoprim-sulfamethoxazole DS twice daily for 3 days, along with increased fluid intake to address dehydration, is recommended. Additionally, cardiology consultation should be considered to evaluate the EKG abnormalities and determine the best course of treatment for the patient's cardiac issues.
