A 75-year-old man with coronaryartery disease presents to the emergencydepartment with abdominalpain and light-headedness. The painbegan as a dull ache 4 days earlierand recently became considerablyworse. The patient denies recenttrauma, fever, nausea, vomiting, and diarrhea.
Use the mnemonic “ALPS” (Amiodarone,Lidocaine, Procainamide, Sotalol)to remember the drugs recommendedin the Advanced Cardiac LifeSupport protocol for the treatment ofstable ventricular tachycardia; theECG complexes in this arrhythmiaresemble mountains.
For more than 30 years, serumdigoxin concentrations (SDCs)have been monitored toensure safe, effective therapy.1,2Although the therapeuticrange for SDCs is often listed as either0.8 to 2.0 ng/mL or 0.5 to 2.0ng/mL, the results of clinical trials inthe 1990s suggest an upper limit of1.0 ng/mL for treatment of heart failure.3-11 An upper limit for the SDC of1.0 ng/mL is also recommendedfor patients who have heart failureand atrial fibrillation with rapid ventricularresponse.
A 75-year-old man with a 120-pack-year smoking history has dyspnea on exertion(eg, when he walks more than 3 blocks or climbs 1 flight of stairs) butnot when he is at rest or asleep. His symptoms have progressively worsenedover the past 3 to 4 years and have been accompanied by a 20-lb weight loss.

A 27-year-old man is referred by an occupational health clinic for evaluation ofa heart murmur. The murmur was detected during a company-mandated examinationfor a flu-like illness that had caused him to miss several days of work.Before the onset of this illness, he had felt well and had no unusual complaints.He denies symptoms of congestive heart failure.
On her eighth day in the hospital for acute pulmonaryembolism, an 88-year-old woman complains of nauseaand abdominal pain and fullness of 12 hours’ duration.The pain is localized to the mid epigastric area and radiatesinto the right lower quadrant. The patient deniesvomiting, melena, and dysuria; she has refused to eat allday.
Q:Based on the latest evidence, what constitutesoptimal management and follow-up for patientswith asymptomatic carotid stenosis?
In recent years, the number of patients with chronic heartfailure has been steadily increasing; this trend reflects thegrowing population of myocardial infarction survivors andpersons over age 65. Many of these patients are evaluated,treated, and followed up in an outpatient setting. This textprovides an in-depth, hands-on approach to the office-baseddiagnosis and management of heart failure. Chapters aredevoted to history taking; economic burden of heart failure;evaluation of dyspnea, edema, palpitations, and ventricularfunction; coronary artery disease and congestive heart failure(CHF); hemodynamic evaluation; exercise performanceevaluation; patient education; drug therapy for symptomaticCHF; assessment and treatment of arrhythmias; biventricularpacing; established, alternative, and emerging therapies;and diastolic heart failure. Echocardiograms, ECG strips,venograms, patient questionnaires, algorithms, diagrams,charts, and tables appear throughout the text.
Q:Should we be prescribing α-blockers to control hypertension in lightof the ALLHAT findings of adverse effects?
A 23-year-old woman has had 2 episodesof syncope during the past month.Her mother witnessed 1 episode inwhich the patient collapsed and lostconsciousness for a few minutes. Sheexperienced tonic-clonic seizure activitybut no subsequent confusion.
A 52-year-old man presented to theemergency department (ED) with a12-hour history of cramping abdominalpain, nausea, vomiting, andwatery, brown diarrhea. Mid upperquadrantpain had begun suddenlythe night before, 1 hour after the patienthad lifted heavy bags of rocks.The GI symptoms persisted with varyingintensity throughout the night.
In her response to a reader’s question about clot prevention in a patient with systemiclupus erythematosus (SLE) and anticardiolipin antibody syndrome,Dr Bonnie Bermas recommends warfarin (CONSULTANT, September 15, 2003,page 1329).
Q:How frequently does hypertension occur in association withobstructive sleep apnea (OSA), and how is OSA best treated?
Heart failure statistics are daunting:550,000 new cases each year, a 1-yearmortality rate of nearly 20%, and annualdirect and indirect costs that total $24.3billion.1 The diverse etiology of heartfailure and the complex, progressivecourse of the disease can make treatmentdecisions daunting as well.
A 27-year-old man is referred by an occupational health clinic for evaluation ofa heart murmur. The murmur was detected during a company-mandated examinationfor a flu-like illness that had caused him to miss several days of work.Before the onset of this illness, he had felt well and had no unusual complaints.He denies symptoms of congestive heart failure.
A 54-year-old man with a history of type 2 diabetes, hypertension, and coronaryartery disease with angina presents to the physician’s office withchest pain. The pain began 3 hours earlier and is associated with diaphoresisand dyspnea. Examination results are unremarkable, except for diaphoresis.A 12-lead ECG reveals normal sinus rhythm with large R waves and horizontalST-segment depression in leads V1 through V3. The patient is given nitroglycerin,aspirin, heparin, morphine, and a β-blocker for noninfarction acutecardiac ischemia and transferred to the local emergency department (ED).
Theophylline has numerouswell-documented and clinicallysignificant drug interactions.Several diseases alsoaffect theophylline clearance.Here, I provide examples of drug anddisease interactions that are most relevantto office practice.
A 60-year-old woman reportsthat she has felt intermittent“fullness” in her face for the past day.This sensation is present when sheis supine on the examination table.She denies shortness of breath, dysphagia,and chest discomfort. Thepatient has a 25 pack-year history ofcigarette smoking.
An 84-year-old woman with hypertension and type 2 diabetes mellitus isbrought to the emergency department (ED) after an episode of nearsyncope.When emergency medical service personnel initially assessed her,blood pressure was 96/60 mm Hg and heart rate was “slow”; however, shehad no symptoms.
A 74-year-old man with a history ofatrial fibrillation presents to hisprimary care physician with dyspneaof 4 days’ duration. The dyspnea developedwhile he was walking as partof his recovery from back surgery forspinal stenosis 1 month earlier. Hebecame progressively short of breathand was unable to carry out his exerciseprogram.
A 56-year-old man with insulin-dependent type 2 diabetes is hospitalized foroperative debridement of an ulcer on his left heel. During the preoperativeevaluation, atrial fibrillation (AF)-with a ventricular rate of 130 beats perminute-is detected.
A42-year-old man with a history of hypertension presents to an outpatientclinic with chest pain that began the day before, after he had worked outat his health club. The discomfort increases when he walks and worsenssomewhat with inspiration. No associated symptoms are noted. Results of aphysical examination are normal; no chest wall tenderness is evident. Becausecertain features of the presentation suggest an acute coronary syndrome, a12-lead ECG is obtained, which is shown here.
