Drinking tea every day may lower risk of ischaemic heart disease

22 Jun 2017Registered users

Daily tea consumption was associated with an 8% relative risk reduction in ischaemic heart disease and a 10% relative risk reduction in major cardiac events, in a large prospective study from China.

Heavy drinkers and teetotallers at increased risk of wide range of cardiovascular diseases

Improving uptake of cardiac rehabilitation

23 Oct 2017Registered users

Data from the National Audit of Cardiac Rehabilitation show that 50% of eligible MI, PCI, and CABG patients do attend cardiac rehabilitation and that figure continues to rise, but the rates for stable angina and heart failure remain low. There is evidence that programmes which have a basis in psychoeducation (goal setting, self-monitoring, relapse prevention) are more likely to achieve long-term behaviour change than those based simply on delivering a fixed agenda of exercise and education. A recent Cochrane review of exercise-based cardiac rehabilitation continues to show the benefit of exercise prescription in terms of cardiovascular mortality, hospital readmission rates, and quality of life.

Assessment and management of CVD risk in adults

23 Oct 2017Registered users

Cardiovascular disease (CVD) affects seven million people in the UK alone. CVD is a term that encompasses coronary heart disease, atrial fibrillation, aortic disease, peripheral artery disease and stroke. Modifiable risk factors for CVD include smoking, abnormal lipid profile, hypertension, diabetes, abdominal obesity, psychosocial factors, diet, alcohol consumption, and lack of physical activity. The INTERHEART study concluded that these factors account for more than 90% of the risk of MI worldwide. Well validated studies have suggested that QRISK2 is a better predictor of a patient’s ten-year risk of CVD compared with the traditionally used Framingham equation.

Early recognition vital in acute coronary syndrome

24 Oct 2016Registered users

Acute coronary syndrome (ACS) includes both ST (STEMI) and non ST elevation (NSTEMI) MI, and unstable angina. Patients with ACS typically present with chest pain; classically central chest pain that radiates to the left arm. Additional symptoms include dyspnoea, nausea, sweating and syncope. However, patients can present atypically with gastric symptoms. These are often more common in patients with diabetes, women and the elderly. A 12-lead ECG should be performed if possible within 10 minutes of presentation or ideally at first contact with the emergency services.

Prompt diagnosis of AF lowers risk of complications

24 Oct 2016Paid-up subscribers

Estimates suggest an AF prevalence as high as 2% in adults with an exponential relationship with increasing age. Opportunistic screening for silent AF is recommended in at-risk groups. AF is associated with a 1.5-2 fold increased risk of death, and is responsible for 20-30% of all strokes. The CHA2DS2-VASc risk stratification score is recommended to assess stroke risk in patients with AF. Risk of severe bleeding with warfarin should also be assessed using the HAS-BLED score.

Management of heart failure with preserved ejection fraction

21 Oct 2015Paid-up subscribers

Heart failure affects nearly one million people in the UK. Half of these patients have normal, or near normal, left ventricular ejection fraction and are classified as heart failure with preserved ejection fraction (HFpEF). Newer imaging techniques have confirmed that systolic function in HFpEF patients is not completely normal, with reduced long axis function and extensive but subtle changes on exercise. Patients are likely to be older women with a history of hypertension. Other cardiovascular risk factors, such as diabetes mellitus, atrial fibrillation and coronary artery disease are prevalent in the HFpEF population.

Playing it safe:exercise and cardiovascular health

21 Oct 2015Registered users

Regular physical activity controls acquired cardiovascular risk factors such as obesity, diabetes mellitus, hypertension and hyperlipidaemia. Exercise is generally associated with a 50% reduction in adverse events from coronary artery disease. Active individuals are at lower risk of developing certain malignancies including cancer of the prostate and the colon, osteoporosis, depression and dementia. Individuals who exercise regularly extend their life expectancy by three to seven years. Healthy individuals should engage in 150 minutes of moderate-intensity aerobic exercise per week. Even lower volumes of exercise confer health benefits, which is highly relevant to individuals with established cardiac disease including heart failure.

Diagnosing heart disease in children and adolescents

22 Jun 2017Registered users

Heart disease in children and adolescents can be congenital, in which structural defects of the heart and major blood vessels are present from birth, acquired, whereby disease develops during life, or genetic, including diseases affecting the heart muscle, electrical system or the aorta. The incidence of congenital heart disease has decreased over the past 30 years, with approximately 1 in 180 babies born with congenital heart disease in the UK each year. Several cardiac diseases are genetic and can manifest in childhood. Most are primary cardiomyopathies, ion channel diseases, coronary artery disease from familial hypercholesterolaemia or aortopathies.

 

Women and cardiovascular risk

Underestimating risk in women delays diagnosis of CVD

21 Mar 2016Registered users

CVD remains the most common cause of mortality in women. There has been an increase in the prevalence of MI in women aged 35 to 54, while a decline in prevalence was observed in age-matched men. Although men and women share classic cardiovascular risk factors the relative importance of each risk factor may be gender specific. The impact of smoking is greater in women than men, especially in those under 50. Diabetes is a more potent risk factor for fatal CHD in women than men.

Women with diabetes at greater risk of CHD than men

23 Jun 2014Registered users

A recent large meta-analysis has confirmed that women with diabetes have more than a 40% higher risk of incident coronary heart disease (CHD) than men. For GPs this is a timely reminder to consider CHD as a high risk in women with diabetes, and to treat risk factors vigorously. This is especially important because routine screening in the healthy population accustoms us to women being generally at lower risk than men using the current CHD risk tools.

MI often presents without chest pain in women

21 Mar 2012Paid-up subscribers

The textbook presentation of myocardial infarction (MI) is not difficult to recognize but in the undifferentiated world of primary care presentations it can be far from clear. This difficulty is compounded by the sex and ethnicity of the patient and the presence of comorbidities such as diabetes. Women are often older than men at hospitalisation for MI and present less frequently with chest pain. It is generally accepted that patients without chest pain tend to present later and are treated less aggressively than those presenting with more typical symptoms. Furthermore, those presenting without pain have almost twice the short-term mortality rate.

Diagnosing and managing pulmonary hypertension

12 Dec 2012Paid-up subscribers

Pulmonary hypertension (PH) is defined as an increase in mean pulmonary arterial pressure ≥ 25 mmHg at rest as assessed invasively by right heart catheterisation. It can affect patients at any age and presents with non-specific symptoms. Accurate diagnosis is important as while PH is a potentially lethal disease it is treatable. Identification of the cause of PH is crucial to ensure that the patient receives appropriate management.

 

Special reports:CVD and stroke

Timely diagnosis of heart failure can improve prognosis

28 Jul 2017Paid-up subscribers

Heart failure is a common, complex clinical syndrome resulting from the impaired ability of the heart to cope with the metabolic needs of the body, leading to breathlessness, fatigue and fluid retention. It is a progressive disease characterised by high levels of morbidity and mortality. The use of plasma concentrations of natriuretic peptides is recommended for ruling out heart failure, as patients with normal natriuretic peptides are unlikely to have heart failure. An echocardiogram is indicated if the natriuretic peptides are elevated, or natriuretic peptide testing is not available.

Erectile dysfunction heralds onset of cardiovascular disease

23 Jun 2016Registered users

Erectile dysfunction (ED) has been shown to share risk factors with cardiovascular disease including age, diabetes mellitus, smoking, hypertension and hypercholesterolaemia, suggesting an underlying vascular pathology. Evidence reveals that there is a potential link between ED and subsequent development of coronary artery disease. ED itself may also increase cardiovascular risk. As ED often predates the development of coronary artery disease this provides GPs with a valuable window of opportunity for risk assessment, subsequent primary prevention and early referral to a cardiologist.

Can my patient with CVD travel to high altitude?

25 Apr 2013Paid-up subscribers

Patients with borderline health should consult a physican before travelling to altitude. The physician will need to know the duration of the trip, ascent profile and how much exercise the patient plans to undertake. The presence of comorbid diseases which reduce oxygenation and ventilation should also be taken into account. Every patient must be assessed on an individual basis, there are no clinical investigations which reliably predict outcome at altitude. Patients should not travel to high altitude immediately after an acute coronary syndrome. Most patients with stable coronary artery disease with a sufficiently high exercise capacity at sea level can go as high as 3,000–3,500 m with only a minimally increased risk.

Improving identification and treatment of atrial fibrillation

12 Dec 2012Paid-up subscribers

Atrial fibrillation is the most common sustained cardiac arrhythmia. One in 40 of the over 45s, 1 in 20 of the over 65s, 1 in 10 of the over 75s and 1 in 5 of the over 85s will have paroxysmal, persistent or permanent atrial fibrillation. Although many individuals will have idiopathic atrial fibrillation with otherwise healthy hearts and no comorbidities, its development is associated with a number of common risk factors. Every patient with a diagnosis of atrial fibrillation should have a physical examination to assess blood pressure and look for signs of valve disease and heart failure. It is routine to check thyroid function and NICE guidelines recommend echocardiographic assessment.

Time to encourage patients to take more exercise

20 Sep 2012Paid-up subscribers

London has just played host to possibly the greatest ever Olympic and Paralympic Games. I enjoyed my small part as a medical volunteer at the Olympic football tournament. Numerous public figures have talked about the potential legacy promoting sport and exercise to the population. This could also be the greatest opportunity for GPs and sport and exercise medicine specialists in the UK to combine forces to deliver our strongest ever campaign to promote physical activity and improve the nation’s health.

Recent developments in the management of heart failure

20 Jun 2012Paid-up subscribers

Because it can be difficult to diagnose heart failure correctly, NICE has given specific advice in its guideline, issued in 2010. In 2012, any patient with suspected heart failure should have the diagnosis confirmed or refuted rapidly, with onward referral for echocardiography and specialist assessment. GP access to BNP/NTproBNP testing is vital to do this effectively. The GP is key to this process – acting as the patient’s advocate for timely diagnosis, making sure drug therapy is introduced and optimised, monitoring the patient’s condition, and identifying when the plan needs to be modified. With access to good diagnosis and good treatment the prognosis of this condition has improved remarkably in the past 20 years but without such modern therapy the syndrome can still be a death sentence.

Targeting CVD risk in chronic connective tissue disease

24 Jan 2012Paid-up subscribers

Chronic inflammatory rheumatological conditions are associated with an increased burden of cardiovascular disease (CVD). In both rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) most excess mortality is cardiovascular. The prevalence of subclinical disease indicates that the atherogenic processes start early in the course of inflammatory disease. Although less data are available regarding the extent of the problem in other inflammatory arthritides or connective tissue diseases, increased CVD risk is also associated with psoriatic arthritis, ankylosing spondylitis, antiphospholipid syndrome and systemic sclerosis. Management of CVD risk in these patient groups is hampered by the complexity of both the underlying disorder and its treatment, and by the lack of clear guidelines for either primary or secondary care teams.

Improving the management of chronic heart failure

24 Nov 2010Paid-up subscribers

NICE has updated its guideline on the management of chronic heart failure. The principal changes from the 2003 guideline include more directive advice on how to improve the quality and timeliness of diagnosis. There is greater encouragement to use beta-blockers, more emphasis on rehabilitation and better access to specialist advice - particularly at the time of diagnosis, admission to hospital, and where symptoms do not respond to first-line therapy with diuretics, ACE inhibitors and beta-blockers. 'A new recommendation is that patients with stable heart failure should be offered a supervised group exercise-based rehabilitation programme designed for such patients. 

GPs have pivotal role in care of stroke patients

15 Feb 2010Paid-up subscribers

GPs play a key role in early recognition of stroke symptoms, thus ensuring that patients receive appropriate acute treatment, early initiation of secondary prevention, lifestyle advice and referral to exercise schemes. It is becoming increasingly recognised that stroke is a chronic disease. So GPs will also be central to managing ongoing risk of recurrent stroke and identifying and managing long-term post-stroke problems.

EECP: A non-invasive therapy for refractory angina

01 Feb 2009Paid-up subscribers

Counter pulsation is a therapy developed from sound physiological principles, widely used in cardiothoracic and interventional centres in the form of intra-aortic balloon pumping (IABP). It has now been developed externally as enhanced external counter pulsation (EECP). EECP is a non-invasive, safe and well tolerated therapy, with very few contraindications.  Currently, EECP is used predominantly in patients with severe angina, who are at high risk and are not suitable for revascularisation. It provides a therapeutic and supportive approach to managing such patients regardless of age and co-morbidity including those with stable heart failure.

Patients with paroxysmal AF at risk of stroke are undertreated

23 Oct 2017Registered users

Patients with paroxysmal atrial fibrillation (AF) eligible for anticoagulation are still less likely to receive anticoagulants than those with persistent or permanent AF, a UK study has found. Both national and European guidelines recommend that anticoagulants are offered to all patients with AF at increased risk of stroke, irrespective of the type of AF. Even in 2015 patients with paroxysmal AF eligible for anticoagulation were still almost 20% less likely to have these drugs prescribed than those patients with persistent or permanent AF.

Does metformin lower CVD risk in type 2 diabetes?

28 Sep 2017Registered users

A recent meta-analysis to evaluate the impact of metformin on cardiovascular disease has been unable to demonstrate convincingly that it is associated with a reduction of risk. The investigators searched Medline, Embase and the Cochrane Library for relevant papers in all languages.  The final yield was ten articles, reporting 13 trials of metformin, virtually all carried out in Northern Europe or North America. In total, 2,079 patients with type 2 diabetes were allocated to metformin and a similar number to comparison groups. All the outcomes, with the exception of stroke, favoured metformin but none achieved statistical significance.

PPIs with aspirin in older patients lowers risk of major bleeds

28 Jul 2017Registered users

A UK prospective population-based cohort study assessed the risk, time course, and outcomes of bleeding on antiplatelet treatment for the secondary prevention of cardiovascular disease in patients of all ages. The authors concluded that in secondary prevention with aspirin-based antiplatelet treatment without routine PPI use, the long-term risk of bleeding at age 75 years or older is higher and more sustained than in the younger age groups included in previous trials, with particularly high risks of disabling or fatal upper GI bleeding. 'Given that half of the major bleeds in patients aged 75 years or older were upper GI, the estimated NNT for routine PPI use to prevent major upper GI bleed is low and co-prescription should be considered in future secondary prevention guidelines,' they say.

Risk of acute STEMI significantly increased in younger smokers

23 Jan 2017Registered users

Smoking is associated with an eight-fold increased risk of acute ST-segment elevation myocardial infarction (STEMI) in those under 50 compared with former and never smokers, a UK study has found. However, the incidence of acute STEMI in former smokers was similar to that in those who had never smoked, adding further evidence to the benefits of quitting smoking.

Antidepressants and cardiovascular risk

23 May 2016Registered users

Selective serotonin reuptake inhibitors (SSRIs) are not associated with an increased risk of cardiovascular events in younger adults with depression, a large UK cohort study has found. Compared with periods of no antidepressant treatment, periods of SSRI treatment were not associated with an increased risk of arrhythmia, stroke or TIA.

Androgen deprivation therapy and cardiovascular risk

24 Sep 2015Registered users

An awareness of CVD risk allows GPs to look proactively at modifiable risk factors in these men, to encourage smoking cessation, weight loss and increased exercise – all of which have been independently associated with improved prostate cancer outcomes in their own right – and to consider medical treatment for risk factors such as dyslipidaemia.

Women with diabetes at greater risk of CHD than men

A recent large meta-analysis has confirmed that women with diabetes have more than a 40% higher risk of incident coronary heart disease (CHD) than men. For GPs this is a timely reminder to consider CHD as a high risk in women with diabetes, and to treat risk factors vigorously. This is especially important because routine screening in the healthy population accustoms us to women being generally at lower risk than men using the current CHD risk tools.

Can radical lifestyle changes in diabetes improve CV outcomes?

25 Jul 2013Paid-up subscribers

A major trial to determine whether intensive lifestyle intervention would reduce cardiovascular (CV) morbidity and mortality in type 2 diabetes patients has been stopped early because of failure to show benefit in the intervention group. Nevertheless, clinicians may confidently advise patients that improvements in diet and activity will reduce weight, the need for medications and the incidence of sleep apnoea and will improve wellbeing.

Is baldness a risk factor for coronary heart disease?

25 Apr 2013Registered users

A recent study has potentially identified another risk factor for coronary disease, that of male pattern baldness (androgenetic alopecia).The authors conclude that vertex baldness is associated with an increased risk of coronary heart disease and the strength of this association is dependent on the severity of baldness. This association appears to hold true for younger patients. It should prompt careful evaluation of other cardiovascular risk factors but to what extent it should modify established cardiovascular risk scores is unclear until further evidence is available. 

Statins underused for primary prevention in older patients

19 Sep 2012Paid-up subscribers

'A treatment-risk paradox where patients become less likely to receive appropriate treatment with advancing age has been observed in the secondary prevention of cardiovascular disease (CVD). This is particularly apparent for cholesterol-lowering treatment with one study showing the likelihood of statin treatment was 6% lower with each year increase in age. However, it is not clear if such a paradox exists in primary prevention and a recent UK study published in the BMJ addresses this issue...'
