RESUMO

BACKGROUND AND AIMS: An electrocardiogram (ECG) is a mandatory test for anyone presenting with loss of consciousness. Many referrals to the first seizure clinic (FSC) are caused by syncope. We assessed the sensitivity of neurologists' ECG reporting in detecting rhythm abnormalities including some potentially life-threatening cardiac conditions. METHODS: We audited patients referred to a FSC in Glasgow over 4 years. All ECGs were interpreted by the attending neurologist as standard practice. Subsequently, two cardiologists reviewed the ECGs independently. RESULTS: Of 160 consecutive patients, 92 patients (58%) were diagnosed as having seizures, 43 (27%) as syncope, and 25 (16%) were unclassified. Twenty eight ECGs thought to be normal by the neurologist were considered abnormal by the cardiologist, including three with long corrected QT interval. The proportion of abnormal ECGs and disparity in reporting between neurologists and cardiologists persisted independent of the underlying diagnosis. CONCLUSION: Reporting of ECGs by non-cardiologists may not be adequately sensitive in picking up potentially life threatening cardiac conditions. Cardiologist input into FSCs is recommended to enhance the diagnostic yield.

RESUMO

Following the UK Academy of Medical Royal Colleges Report on seven day consultant present care, the Royal College of Physicians and Surgeons of Glasgow held a symposium to explore clinicians' views on the ways in which clinical care should best be enhanced outside 'normal' working hours. In addition, a survey of members and fellows was undertaken to identify the tests which would make the greatest impact on care out of hours. Key messages were: (a) that seven-day consultant delivered care would not achieve the desired benefit to patient care if introduced in isolation from other inter-relating factors. These include alternatives to hospital admission, enhanced nursing support, increased junior medical, pharmacy, social care and ambulance availability and greater access to selected diagnostic services; (b) that the care of hospital inpatients is a service which is one part of the totality of secondary care provision. Any significant change in the deployment of staff for inpatient care must be carefully managed so as not to result in a reduced quality of care provided by the rest of the system.

RESUMO

BACKGROUND: Studies have demonstrated considerable accuracy of multi-slice CT coronary angiography (MSCT-CA) in comparison to invasive coronary angiography (I-CA) for evaluating coronary artery disease (CAD). The extent to which published MSCT-CA accuracy parameters are transferable to routine practice beyond high-volume tertiary centres is unknown. AIM: To determine the accuracy of MSCT-CA for the detection of CAD in a Scottish district general hospital. DESIGN: Prospective study of diagnostic accuracy. METHOD: One hundred patients with suspected CAD recruited from two Glasgow hospitals underwent both MSCT-CA (Philips Brilliance 40 × 0.625 collimation, 50-200 ms temporal resolution) and I-CA. Studies were reported by independent, blinded radiologists and cardiologists and compared using the AHA 15-segment model. RESULTS: Of 100 patients [55 male, 45 female, mean (SD) age 58.0 (10.7) years], 59 and 41% had low-intermediate and high pre-test probabilities of significant CAD, respectively. Mean (SD) heart rate during MSCT-CA was 68.8 (9.0) bpm. Fifty-seven per cent of patients had coronary artery calcification and 35% were obese. Patient prevalence of CAD was 38%. Per-patient sensitivity, specificity, positive and negative (NPV) predictive values for MSCT-CA were 92.1, 47.5, 52.2 and 90.6%, respectively. NPV was reduced to 75.0% in the high pre-test probability group. Specificity was compromised in patients with sub-optimally controlled heart rates, calcified arteries and elevated BMI. CONCLUSION: Forty-Slice MSCT-CA has a high NPV for ruling out significant CAD when performed in a district hospital setting in patients with low-intermediate pre-test probability and minimal arterial calcification. Specificity is compromised by clinically appropriate strategies for dealing with unevaluable studies. Effective heart rate control during MSCT-CA is imperative. National guidelines should be utilized to govern patient selection and direct MSCT-CA reporter training to ensure quality control.

RESUMO

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is of increasing prevalence. The presence of AF complicates the management of patients presenting as medical emergencies. OBJECTIVE: To assess the prevalence of AF and current investigation and management strategies in unselected acute medical admissions. DESIGN: Prospective survey of all acute medical admissions over 22 days. SETTING: Stobhill Hospital--district general hospital in north Glasgow. SUBJECTS: Five hundred and seven consecutive acute medical admissions. RESULTS: Of the 507 patients, 47 (9.3%) had AF. AF was a new diagnosis in five patients (11.0%). The most common presenting features were dyspnoea and chest pain. The principal underlying medical conditions were hypertension and ischaemic heart disease. AF was the primary reason for admission in six patients (12.8%) and a documented reason for admission in 11 patients (23.4%). Thyroid function tests were or had previously been performed in 45 patients (95.7%). Twenty-four patients (51.1%) underwent echocardiography or had done so previously. Twenty-two patients (46.8%) received anticoagulation with warfarin. Ten patients (21.3%) should have received warfarin by standard guidelines but did not. No patient received warfarin inappropriately. Rate control was used in 40 patients (85.1%). Rhythm control was attempted in four patients (8.5%). CONCLUSION: AF is common amongst emergency admissions to district general hospitals and has significant resource implications. Improvements are needed both in the use of echocardiography and in the administration of anticoagulant therapy.

RESUMO

BACKGROUND: Pericardial effusions frequently present challenging clinical dilemmas. Whether or not to drain an effusion, and if so by what method, are two common decisions facing cardiologists. We performed a survey to evaluate pericardiocentesis practice in the United Kingdom (UK). METHODS: A total of 640 questionnaires were sent to all cardiologists in the UK Directory of Cardiology in March 2003. RESULTS: A total of 274 (43%) completed questionnaires were returned, 88% from consultants, equally distributed between tertiary referral centres and district general hospitals. More than 1500 procedures were performed, largely using a paraxiphoid approach (89%). Clinical tamponade was the commonest indication for pericardiocentesis (83%). However, the majority of respondents (69%) considered echocardiographic features alone an indication for pericardiocentesis, even in the absence of clinical tamponade. The commonest perceived indications for drainage were right ventricular diastolic collapse and right atrial collapse (69% and 33% of respondents respectively). For guidance, 82% use echocardiography, either alone or with fluoroscopy or the electrocardiogram (ECG) injury trace. 11% employ fluoroscopy alone or with the ECG injury trace. The remaining 11% stated that they would use the ECG injury trace alone or use no guidance. Using the ECG injury trace alone is said by the European Society of Cardiology (ESC) guidelines to offer an inadequate safeguard. Reported complications included ventricular puncture (n = 12, 0.8%) and hepatic damage (n = 4, 0.3%). CONCLUSION: Pericardiocentesis practice varies substantially in the UK. Many cardiologists would perform pericardiocentesis based on echocardiographic features alone. 11% of cardiologists use guidance that is considered inadequate by the ESC guidelines.

RESUMO

Atrial fibrillation (AF) is the most common sustained tachyarrhythmia and its prevalence is increasing. It is an independent risk factor for stroke and is associated with significant morbidity and mortality. AF currently accounts for 1% of NHS expenditure. The management of AF has a broad evidence base and both the American College of Cardiology/American Heart Association/European Society of Cardiology (ACC/AHA/ESC) and the National Institute for Clinical Excellence (NICE) have recently published guidelines. Some controversy persists regarding stroke risk stratification and appropriate anticoagulation regimes although a general consensus is now emerging. Rate and rhythm control strategies have been shown to be comparable in terms of clinical outcomes. Current anti-arrhythmic drugs have limited efficacy and significant side-effect profiles. Electrophysiological and surgical interventions have a role in both strategies. This article broadly reviews the evidence for different management strategies in AF and presents a practical approach to treatment in light of the recently published national and international guidelines.

RESUMO

BACKGROUND: Electrocardiographic left ventricular hypertrophy (ECG LVH) is a powerful independent predictor of cardiovascular morbidity and mortality in hypertension. OBJECTIVE: To determine the contemporary prevalence and prognostic implications of ECG LVH in a broad spectrum of patients with heart failure with and without reduced left ventricular ejection fraction (LVEF). METHODS AND OUTCOME: The Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) programme randomised 7599 patients with symptomatic heart failure to receive candesartan or placebo. The primary outcome comprised cardiovascular death or hospital admission for worsening heart failure. The relative risk (RR) conveyed by ECG LVH compared with a normal ECG was examined in a Cox model, adjusting for as many as 31 covariates of prognostic importance. RESULTS: The prevalence of ECG LVH was similar in all three CHARM trials (Alternative, 15.4%; Added, 17.1%; Preserved, 14.7%; Overall, 15.7%) despite a more frequent history of hypertension in CHARM-Preserved. ECG LVH was an independent predictor of worse prognosis in CHARM-Overall. RR for the primary outcome was 1.27 (95% confidence interval (CI) 1.04 to 1.55, p = 0.018). The risk of secondary end points was also increased: cardiovascular death, 1.50 (95% CI 1.13 to 1.99, p = 0.005); hospitalisation due to heart failure, 1.19 (95% CI 0.94 to 1.50, p = 0.148); and composite major cardiovascular events, 1.35 (95% CI 1.12 to 1.62, p = 0.002). CONCLUSION: ECG LVH is similarly prevalent in patients with symptomatic heart failure regardless of LVEF. The simple clinical finding of ECG LVH was an independent predictor of a worse clinical outcome in a broad spectrum of patients with heart failure receiving extensive contemporary treatment. Candesartan had similar benefits in patients with and without ECG LVH.

RESUMO

AIMS: The significance of left ventricular hypertrophy in hypertension is well documented, being an independent risk factor for cardiovascular morbidity and mortality. Normal values for left ventricular mass and partition values for left ventricular hypertrophy come from measurements obtained by fundamental echocardiography. Secondary harmonic imaging improves definition of cardiac borders. We hypothesise that this overestimates left ventricular mass compared to fundamental imaging. METHODS AND RESULTS: Thirty patients had four parasternal long-axis M-modes performed, two using 1.7 mHz output frequency, receiving at two octaves higher and two using fixed frequency of 2.5 mHz (fundamental imaging). Absolute left ventricular mass and left ventricular mass index were calculated for each modality. Intra-observer variability was <7%. Range on fundamental imaging was 54-264 g/m2 compared to 80-293 g/m2 on secondary harmonic imaging. Mean left ventricular mass index for the group was 118 g/m2 (fundamental imaging) vs 147 g/m2, P<0.001. Twenty-nine of 30 patients had higher left ventricular mass index on secondary harmonic imaging compared to fundamental imaging. Left ventricular mass index was an average of 26% higher on secondary harmonic imaging, range (-7 to 65%) corresponding to average absolute left ventricular mass difference of 55 g. Eleven of 30 patients had left ventricular hypertrophy on fundamental imaging and 17/30 on secondary harmonic imaging. CONCLUSION: Secondary harmonic imaging overestimates left ventricular mass index compared to fundamental imaging. Normal left ventricular mass index range is based on equations using fundamental imaging measurements. Management decisions and prognostic implications made on the basis of raised left ventricular mass index using secondary harmonic imaging should be done so with caution.

RESUMO

Rapid access chest pain clinics are expanding across the country with marked resource implications despite a paucity of data regarding their efficacy. Early assessment of patients in this manner potentially delays review of patients referred via the traditional route. We conducted a prospective observational study of patients referred with chest pain to the Cardiology Outpatient Department over a four-week period in a District General Hospital to compare demographics and outcomes in patients referred to the rapid access with those referred to the general cardiology clinics. There were no significant differences in baseline demographics, exercise test result or clinic outcome. Both populations were low risk. Discussion is needed between primary and secondary care to achieve a consensus as to the purpose of a rapid access system and how best to utilise the service appropriately. Further studies are required to assess the efficacy and health economics of this system.

RESUMO

Atrial fibrillation (AF) is a common arrhythmia associated with increased morbidity and mortality. Current practice aims to restore sinus rhythm (SR), although the question of whether rate or rhythm control is the optimal approach for these patients remains unanswered. The most established method of restoring SR in patients with AF of duration greater than 48 hours is external direct-current cardioversion (DCC). This is a descriptive paper summarising how we utilised the hospital's day surgery unit for the provision of DCC for patients with AF in order to provide a more efficient service and allow an increased number of procedures to be conducted. We describe the reasons for setting up the service and the methods involved. We also summarise the advantages associated with this new system.

RESUMO

The objective was to prospectively validate a method of increasing the sensitivity, specificity and negative predictive value of a normal ECG in the exclusion of left ventricular systolic dysfunction by the addition of clinical history. We performed a prospective three year study of all referrals to our direct access ECHO service for assessment of LV function. The ECG was reported blind of the result of the ECHO, history of MI or not was noted, and result of the ECHO predicted. Over three years 416 patients were assessed for the presence or absence of left ventricular systolic dysfunction and consequent changes in clinical management. A total of 320(77%) of patients referred with suspected left ventricular dysfunction were found to have normal left ventricular function. Of the 250(60%) patients treated prior to referral for assessment, 183(73%) were treated inappropriately. The combination of a normal ECG and a negative history of myocardial infarction had a sensitivity of 98% and a negative predictive value of 99% in the assessment of LV function. This was an improvement over a normal ECG alone. Our study shows that diagnosis and treatment of heart failure in the community remains sub-optimal. The combination of a normal ECG and no previous history of myocardial infarction is shown to be a sensitive and accurate predictor of normal left ventricular function. If adopted by general practitioners this would be a valuable method of optimising the use of echocardiography in patients with suspected left ventricular dysfunction.

RESUMO

Hypertension is one of the major risk factors for coronary artery disease. This risk is considerably magnified by the presence of left ventricular hypertrophy. The likeliest dominant factor in this increased risk is myocardial ischaemia, the recognition of which is of key importance. Antihypertensive agents ideally should also protect against occurrence of the clinical syndromes associated with coronary artery disease.

RESUMO

BACKGROUND: Electrocardiography is the fundamental investigation for decision making regarding thrombolytic treatment in acute myocardial infarction (MI). Increasing the accuracy of ECG analysis by input from consultant staff may assist in management decisions in patients with suspected MI. AIMS: To evaluate a system whereby out of hours ECGs can be faxed to the consultant to aid in decision making regarding thrombolytic treatment. METHODS: 112 patients with suspected MI were assessed on admission by the senior house officer (SHO) who faxed to a cardiology consultant the ECG trace and a predesigned form with information on: clinical assessment of the patient; interpretation of the ECG; and views regarding administration of thrombolytic treatment including choice of agent. The consultant reviewed the information and communicated his views to the SHO. Subsequent diagnosis was recorded in all patients and the forms were analysed in regard to areas of agreement and disagreement between the SHO and the consultant. RESULTS: A diagnosis of MI was confirmed in 52 of the 112 patients (46.4%). The consultant agreed with the SHO's decision on thrombolysis in 98 patients (87.5%). The reason for disagreement in the remaining 14 patients (12.5%) was SHO misinterpretation of the ECG (10 patients) and clinical assessment (four patients). Eight patients were saved unnecessary thrombolytic treatment and four received it when they otherwise would not have. Additionally the choice of thrombolytic agent was changed in six patients from streptokinase to tissue plasminogen activator. CONCLUSION: The use of fax machine assists in decision making with regard to thrombolytic treatment and provides support to junior doctors in what can be a difficult, yet critical decision.

RESUMO

Four hundred seventy-three patients with acute myocardial infarction (AMI) were treated with either saruplase (80 mg/hour, n = 236) or alteplase (100 mg every 3 hours, n = 237). Comedication included heparin and acetylsalicylic acid. Angiography was performed at 45 and 60 minutes after the start of thrombolytic therapy. When flow was insufficient, angiography was repeated at 90 minutes. Coronary angioplasty was then performed if Thrombolysis In Myocardial Infarction (TIMI) trial 0 to 1 flow was seen. Control angiography was at 24 to 40 hours. Baseline characteristics were similar. Angiography showed comparable and remarkably high early patency rates (TIMI 2 or 3 flow) in both treatment groups: at 45 minutes, 74.6% versus 68.9% (p = 0.22); and at 60 minutes 79.9% versus 75.3% (p = 0.26). Patency rates at 90 minutes before additional interventions were also comparable (79.9% and 81.4%). Angiographic reocclusion rates were not significantly different: 1.2% versus 2.4% (p = 0.68). After rescue angioplasty, angiographic reocclusion rates of 22.0% and 15.0% were observed. Safety data were similar for both groups. Thus, (1) early patency rates were high for saruplase and alteplase treatment, (2) reocclusion rates for both drugs were remarkably low, and (3) complication rates were similar. Thus, saruplase seems to be as safe and effective as alteplase.
