Current status of outpatient heart failure management in Egypt and recommendations for the future.

Heart failure (HF) represents one of the greatest healthcare burdens worldwide, and Egypt is no exception. HF healthcare programmes in Egypt still require further optimization to enhance diagnosis and management of the disease. Development of specialized HF clinics (HFCs) and their incorporation in the healthcare system is expected to reduce HF hospitalization and mortality rates and improve quality of care in Egypt.

Cardiac resynchronization therapy: dyssynchrony imaging from a heart failure perspective.

Purpose Of Review: To review the evidence for and against imaging as a means of selecting patients for cardiac resynchronization therapy (CRT).

Recent Findings: There is no evidence that either the QRS interval on the surface ECG or dyssynchrony measured by imaging is of any practical value in predicting the clinical response to CRT in patients with a dilated and dysfunctional left ventricle. Careful assessment of the patient, so that therapy can be logically aligned with treatment goals, such as improving symptoms or prognosis, is the only useful method for selecting patients.

Should patients who have persistent severe symptoms receive a left ventricular assist device or cardiac resynchronization therapy as the next step?

Currently, cardiac resynchronization therapy (CRT) should be considered before a left ventricular assist device for most patients who have moderate or severe left ventricular systolic dysfunction and have not responded symptomatically to conventional pharmacologic measures. There is little evidence that the severity of cardiac dyssynchrony as measured using current techniques is useful in predicting the benefits of CRT. QRS duration on the surface ECG is a surrogate marker of the severity of the left ventricular ejection fraction as well as of several types of dyssynchrony.

Cardiac resynchronization therapy or atrio-biventricular pacing-what should it be called?

Reduced cardiac efficiency caused by suboptimal synchronization of the heart's normal contraction might contribute to the development of or exacerbate heart failure. Conceptually and in practice cardiac dyssynchrony is complex. Recent studies have shown that atrio-biventricular pacing can improve cardiac synchrony in many patients and improve cardiac function, symptoms and exercise capacity, and reduce morbidity and mortality substantially.
