Question of the Week #483

BACKGROUND:

Beta-blockers reduce mortality in patients who have chronic heart failure, systolic dysfunction, and are on background treatment with diuretics and angiotensin-converting enzyme inhibitors. We aimed to compare the effects of carvedilol and metoprolol on clinical outcome.

METHODS:

In a multicenter, double blind, and randomized parallel group trial, we assigned 1511 patients with chronic heart failure to treatment with carvedilol (target dose 25 mg twice daily) and 1518 to metoprolol (metoprolol tartrate, target dose 50 mg twice daily). Patients were required to have chronic heart failure (NYHA II-IV), previous admission for a cardiovascular reason, an ejection fraction of less than 0.35, and to have been treated optimally with diuretics and angiotensin-converting enzyme inhibitors unless not tolerated. The primary endpoints were all-cause mortality and the composite endpoint of all-cause mortality or all-cause admission. Analysis was done by intention to treat.

FINDINGS:

The mean study duration was 58 months (SD 6). The mean ejection fraction was 0.26 (0.07) and the mean age 62 years (11). The all-cause mortality was 34% (512 of 1511) for carvedilol and 40% (600 of 1518) for metoprolol (hazard ratio 0.83 [95% CI 0.74-0.93], p=0.0017). The reduction of all-cause mortality was consistent across predefined subgroups. Incidence of side effects and drug withdrawals did not differ by much between the two study groups.

 

  1. To which of the following patients are the results of this clinical trial applicable?
    1. A 62-year-old male with primarily diastolic congestive heart failure.
    2. A 75-year-old female with systolic dysfunction and an EF of 45%.
    3. A 56-year-old male with NYHA class I systolic heart failure.
    4. A newly diagnosed 66-year-old male who has yet to begin treatment for his NYHA class II systolic heart failure.
    5. A 68-year-old male with NYHA class II systolic heart failure and EF 30%.

 

Question of the Week # 174

174) A 52 year old African-american woman is seen in the office during a regular follow-up visit. Her history is significant for diabetes mellitus and hypertension. She has been suffering from cough over the past two weeks.  She feels that there is a tickle at the back of the throat which leads to paroxysms of coughing. Her medications include Aspirin, Glipizide, atorvastatin, enalapril and Hydrochlorthiazide.  Enalapril was started 3 weeks ago at a low dose of 5mg/day. On examination, blood pressure is 132/90 mm Hg seated and standing.  Her physical examination is normal.  Laboratory values reveal a serum creatinine concentration of 1.8mg/dl. Her baseline creatinine  1 month ago was 1.5mg%. Which of the following is not an indication to stop ACE inhibitor?

A)     Swelling of the lips and tongue

B)      20% increase in serum creatinine

C)      Intractable severe cough

D)     Serum potassium of 6.5mmol/L

E)      Hypovolemia with shock

Question of the Week # 148

148)  A 55 year old nurse has recently been exposed to an in-patient with active Tuberculosis about 2 months ago. Her tuberculin skin test was negative a year ago however; the skin test reveals an 12 mm induration at this time. A chest x-ray is normal. She denies any cough or fever or weightloss. A comprehensive metabolic panel is within normal limits. She is started on Isoniazid for the treatment of latent tuberculosis. Two weeks after the therapy, patient develops edema in the face and neck, maculopapular rash, lymphadenopathy, asthenia, and a fever of 38°C. Laboratory tests reveal a WBC count 20k/µl with a differential showing neutrophils of 50%, eosinophils of 30% and lymphocytes 20%. The most appropriate next step in management:

A)     Start antifungal therapy

B)      Discontinue Isoniazid and re-administer after de-sensitization

C)      Discontinue Isoniazid and administer Rifampin for four months

D)     Start Metronidazole

E)      Change to multi-drug therapy,  Isoniazid , Pyrazinamide, Rifampin and Ethambutol
