Atrial Fibrillation

A 64-year-old woman with a history of diabetes, hypertension, and lymphoma was admitted to the hospital with a dull headache, conjunctival congestion, and slight dyspnea. Her pulse rate was 96 beats per minute; blood pressure, 146/68 mm Hg; and respiration rate, 22 breaths per minute. She also had increased jugular venous distention; cardiovascular and chest examination findings were normal. Edema of both arms and dilated blood vessels on the anterior chest wall were noted.

This simple technique can quickly reduce leg edema. Instruct the patient to place a chair on abed as shown, lay a pillow on the back of the chair, then lie down with legs elevated on the pillowcoveredchair back. (Do not use in patients with congestive heart failure; volume overload andpulmonary edema may result.)

A 65-year-old woman with a long history of hypertension treated with metoprolol and felodipine complained of dizziness, headache, nausea, and vomiting of acute onset. Her blood pressure was 220/110 mm Hg. She was drowsy and unable to stand or walk.

Heart failure(HF), the mostcommon Medicarediagnosisrelatedgroup,has a significant and growingimpact on health careresources. The incidenceof HF has tripled during thelast decade. Almost 5 millionAmericans have HF, and anestimated 500,000 new casesare diagnosed yearly. Thelifetime risk of HF is about20%.1 Drug therapy has improvedconsiderably in recentyears, but the magnitudeand severity of theproblem has created a needfor newer therapies--particularlysince HF is associatedwith an increased risk ofsudden death and a diminishedquality of life.2

A 58-year-old man recently underwent coronary artery bypass graft (CABG)surgery after emergent cardiac catheterization for a myocardial infarction revealeddiffuse 3-vessel disease.

A 65-year-old woman experienced dyspnea, dizziness, and left pleuritic pain several hours after falling down a flight of stairs. Shallow breathing and increased tenderness of the left thoracic wall were evident with palpation. Decreased breath sounds on the left and dullness on percussion were also noted.

Long-term oxygen therapy (LTOT) improves both the length and qualityof life of hypoxemic patients with COPD. It is the only therapy thatclearly increases survival for selected patients with advanced stable COPD.

For 2 days, a 79-year-old man with a history of congestive heart failure experienced abdominal pain, diarrhea, and dark red rectal bleeding. The pain was localized to the left lower quadrant.

Q:Should I avoid angiotensin-converting enzyme (ACE) inhibitors in mypatients with progressive renal insufficiency?

An 82-year-old woman who had recentlyarrived from Japan presented to theemergency department with a 3-dayhistory of abdominal pain that beganimmediately after she swallowed severalpills with a small amount of water.The severe, intermittent pain radiatedto the patient’s back and worsened withmeals. The patient denied chills, nausea,vomiting, coughing, diarrhea, andconstipation. She had well-controlledtype 2 diabetes mellitus and hypercholesterolemia,and had undergone anappendectomy 50 years earlier.

Q:Many of my patients appear to have white-coathypertension: their pressure is elevated whenmeasured in my office-but normal when measured athome. Am I ignoring significant hypertension if I do nottreat these patients? Or am I overtreating if I do treat?

A 37-year-old woman presents to the emergency departmentwith a diffuse, sharp, pounding headache,which started 2 hours earlier. She rates her discomfort as4 on a scale of 1 to 10. Neck muscle soreness is also present,but the pain does not radiate.

Over the past 20 years, obesity has reached epidemic proportions in the United States and throughout the world. The need for effective prevention and treatment is thus more urgent than ever.

A 76-year-old woman had a 40-year history of rheumatoid arthritis (RA). She had repeatedly refused treatment with disease-modifying drugs, including methotrexate. Nodules began to develop 15 years after the initial diagnosis; they recurred after surgical removal.

For 2 months, a 31-year-old woman had had dyspnea anddull, continuous retrosternal pain. She was admitted to thehospital, and a helical CT scan of the thorax identified asaddle pulmonary embolism. An ultrasonogram revealeddeep venous thrombosis (DVT) in the left leg. Intravenousheparin was given; the patient was discharged,and warfarin was prescribed.

The past several years have witnessedimportant advances in the evaluationand management of chronic heart failure(HF). Drugs such as β-blockersand spironolactone have been shownto reduce morbidity and mortality, andstrategies that employ new devices,such as pacing and defibrillator therapy,are evolving. This has promptedthe American College of Cardiology(ACC)/American Heart Association(AHA) to update guidelines first publishedin 1995.1 The guidelines highlightthe importance of early and accuraterecognition of the clinical syndromeof chronic HF and offer anoutline for evidence-based therapeuticdecision making.

A 65-year-old woman with metastatic adenocarcinoma of the colon was undergoing chemotherapy following a colectomy and a hepatic wedge resection. The physical examination and laboratory data were unremarkable.
