A variety of clinical syndromes can cause T-wave inversions; these range from life-threatening events, such as acute coronary ischemia, pulmonary embolism, and CNS injury, to entirely benign conditions. Here: a discussion of conditions that can cause T-wave inversions in leads V1 through V4.
BOSTON -- Multiple biomarkers such as C-reactive protein, homocysteine, and B-type natriuretic peptide add nuance but little substance to time-honored prognostic cardiovascular risk factors, researchers here reported.
CHAPEL HILL, N.C. -- Low levels of LDL cholesterol appear to confer a greater risk of Parkinson's disease, suggesting that it's possible to have too little of a bad thing, researchers here reported.
Despite Pfizer's high-profile drug failure, boosting HDL still a key heart-disease strategy. Several drugs in development use various mechanisms to raise levels of "good cholesterol." Meanwhile, physicians can do plenty right now to raise patients' HDL levels.
A 73-year-old woman presents with apainless, nonpruritic rash of recent onseton her right lower ankle. She has nofever, chills, nausea, vomiting, malaise,or other systemic complaints. Her medicalhistory includes fibromyalgia, osteoarthritis,stable angina, and anxiety;there is no history of connective tissuedisease.
I enjoyed Dr Henry Schneiderman’s “What’s Your Diagnosis?” case of an elderly woman with severe facial ecchymoses from a fall. Would Dr Schneiderman elaborate on several points about that case? This woman did not trip or complain of dizziness before she fell. What caused her to fall?
Excessive sweating, or hyperhidrosis, can be primary or secondary. Cardiac disease can cause hyperhidrosis. If the results of his laboratory workup are normal and he does not show evidence of leukemia, lymphoma, infection, or diabetes, then I would try treating him for primary hyperhidrosis.
Amiodarone, a class III antiarrhythmic, has become the drug of choice for the management of supraventricular and ventricular arrhythmias.1,2 Although not an FDA- approved indication, the use of amiodarone to treat atrial fibrillation is supported by practice guidelines from the American College of Cardiology/ American Heart Association (AHA) and the European Society of Cardiology.
A 49-year-old man presents with recurring facial pain of 6 months' duration. The pain initially occurred several times per week; it now occurs as often as several times per day. The paroxysmal pain is intense and incapacitating but abates within several minutes. It occurs in the right maxillary region and lower jaw and is sharp and lancinating. Hard chewing and teeth cleaning are the usual precipitating events. Between episodes, the patient is asymptomatic, without numbness or deficit in the affected region.
A 26-year-old otherwise healthy man presents to the emergency department with a 3- to 4-hour history of left-sided chest pain. The pain is pleuritic and accompanied by nausea and discomfort in the left arm.
A 26-year-old woman with dull left-sided chest pain, nausea, body aches, and low-grade fever is admitted to the hospital. She has been to other emergency departments (EDs) in the area recently with similar complaints and was sent home with diagnoses of anxiety and costochondritis.
When your patient presents with chest pain and other symptoms of an acute coronary syndrome (ACS), yet a standard 12-lead ECG shows no evidence of ST-segment elevation myocardial infarction (STEMI), you may face a diagnostic dilemma. The patient could have a non-STEMI ACS for which conservative treatment will suffice--or he could have a STEMI in an electrocardiographically "silent" area and need acute reperfusion therapy.

Approximately 90% of cases of lung cancer are attributable to smoking-either directly or as a result of passive exposure. Fifty percent of smokersdie of a smoking-related disease. The 4 most common causes of death-heartattack, lung cancer, chronic obstructive pulmonary disease, and stroke-areall associated with smoking. More lung cancer is diagnosed in former than incurrent smokers.1 The risk of lung cancer decreases each year following smokingcessation, but former heavy smokers will always have a higher risk thannonsmokers.
The authors report the incidental finding of a persistent left superior vena cava (PLSVC) during the routine placement of a left subclavian central line in an elderly man with acute renal failure.
A 29-year-old man presents with a recent episode of light-headedness of sudden onset. Although he denies associated loss of consciousness, witnesses report that he was briefly unresponsive to verbal stimuli. He also denies chest pain, dyspnea, palpitations, and diaphoresis; he is currently asymptomatic.
Q: What is the lowest acceptable diastolic blood pressure (DBP) in a patient with systolic hypertension who is older than 65 years?

What is the lowest acceptable diastolic blood pressure (DBP) in a patient with systolic hypertension who is older than 65 years?
My patient has diabetes, end-stage renal disease, and congestive heart failure (CHF)--and does not want to use insulin. What oral medication(s) would be considered optimal in this setting?
In patients with diabetes who have end-stage renal disease and CHF, the choice of oral medications is limited because metformin is contraindicated. Glipizide has a 5% renal clearance and is relatively safe. Studies suggest that glimepiride is the safest of the sulfonylureas.
ABSTRACT: Subclinical hypothyroidism is associated with elevated low-density lipoprotein (LDL) cholesterol levels and several factors related to atherosclerosis, including increased C-reactive protein levels and impaired endothelium-dependent vasodilatation. However, considerable controversy exists about screening for and treating this thyroid disorder. Thyroxine therapy lowers elevated LDL cholesterol levels in patients whose serum thyroid-stimulating hormone (TSH) concentrations are higher than 10 mIU/L ; thus, most experts recommend treatment for such patients. However, there is no consensus regarding the management of patients with TSH levels of less than 10 mIU/L. Although the evidence supporting treatment of these patients is not compelling, it is reasonable to offer a therapeutic trial of thyroxine to those who have symptoms.
ABSTRACT: Our knowledge of chronic diseases has advanced significantly in recent decades, but patient outcomes have not kept pace. This is largely because the traditional acute care model does not adequately address the needs of patients with chronic disease. Patients play an active role in the management of chronic disease, and successful outcomes are highly dependent on adherence to treatment. Thus, clinicians need to have skills in coaching and encouraging as well as an awareness of factors in patients' backgrounds that are likely to affect their ability or willingness to follow treatment plans. Provider- and system-related factors, such as lack of reimbursement for counseling and high copayments, can also act as barriers to compliance. Among the strategies that can improve adherence are the use of community resources, multidisciplinary approaches, and regular follow-up.
