Multilead ST-segment monitoring in patients with acute coronary syndromes: a consensus statement for healthcare professionals. ST- Segment Monitoring Practice Guideline International Working Group.

BACKGROUND: ST-segment monitoring is underused by healthcare professionals for patients with acute coronary syndromes treated in emergency departments and intensive care units. OBJECTIVE: To provide clinically practical consensus guidelines for optimal ST-segment monitoring. METHODS: A working group of key nurses and physicians met in Dallas, Tex, in November 1998. RESULTS: Consensus was reached on who should and should not have ST monitoring, goals and time frames for ST monitoring in various diagnostic categories, what electrocardiographic leads should be monitored, what equipment requirements are needed, what strategies improve accuracy and clinical usefulness of ST monitoring, and what knowledge and skills are required for safe and effective ST monitoring. CONCLUSIONS: Because changes in the ST segment can shift among various electrocardiographic leads in the same person over time owing to different ischemic mechanisms, 12-lead ST monitoring is recommended. Recommended monitoring times are as follows: myocardial infarction or unstable angina, 24 to 48 hours or until patient is event-free for 12 to 24 hours; chest pain prompting a visit to an emergency department, 8 to 12 hours; catheter-based interventions with less definitive interventional outcomes requiring monitoring in an intensive unit, 6 to 12 hours; and cardiac surgery or noncardiac surgery in patients with coronary disease or risk factors, 24 to 48 hours. An ST measurement point of J + 60 ms makes it unlikely that measurement will coincide with the upslope of the T wave, even in patients with sinus tachycardia. Accurate and consistent lead placement and careful electrode and skin preparation are imperative to improve the clinical usefulness of ST monitoring.

A systematic approach to erectile dysfunction in the cardiovascular patient: a consensus statement.

Sexual activity is no more stressful to the heart when compared with a number of other natural daily activities, e.g. walking one mile on the level in 20 minutes. The cardiac risk of sexual activity in patients diagnosed with cardiovascular disease is minimal in properly assessed and advised patients. Erectile dysfunction (ED) is common, affecting 10% of men aged 40-70 years and increases in frequency with age. ED and cardiovascular disease share many of the same risk factors and often coexist. ED in the diagnosed cardiovascular patient should be identified by routine questioning in general practice. Modern therapies can restore a sexual relationship in the majority of patients with ED and can lead to a substantial improvement in quality of life. The majority of patients assessed to be at low or intermediate cardiac risk, as defined later in this paper (Table 4), can be effectively managed in primary care. Primary care treatment for ED in patients defined as high risk can be initiated following a specialist opinion and/or confirmation that the patient's cardiovascular condition is stabilised. There is no evidence that currently licensed treatments for ED add to the overall cardiovascular risk in patients with or without diagnosed cardiovascular disease.
