NHS England/NHS Improvement: After-care needs of inpatients recovering from COVID-19 [Added 12 June 2020]

Last updated 3 August 2020

  • This guidance includes the following therapeutic areas: respiratory, cardiology, neurology, mental health, endocrinology and urology.
  • There is no medication-related information within the neurology, mental health, endocrinology or urology sections.
  • Guidance for management of patients’ physical respiratory needs is given on pages 7-13.
  • Includes recommendations on anticoagulation for patients with pulmonary embolic disease.
  • Reference made to patients requiring cardiac assessment pre-discharge plus plan – with optimisation of medications listed on page 14.

NHS England/ NHS Improvement: Clinical guide for the management of cardiology patients during the coronavirus pandemic

Last updated 20 March 2020

  • Issues requiring admission and ongoing management will be prioritised eg myocardial infarction, class IV heart failure, arrhythmias (such as uncontrolled AF or VT), endocarditis; pathways must be expedited to allow rapid treatment and discharge.
  • All elective admissions and day cases should be deferred unless absolutely necessary.
  • For outpatients, consideration should be given to the urgency of appointment, the requirement for diagnostics and the need for face-to-face contact; where possible, appointments should be conducted remotely and non-urgent appointments deferred, particularly those requiring diagnostics for surveillance.
  • Advises on specific areas of cardiology services e.g. bradycardia pacing, ICD and CRT implants, elective and primary PCI, ablation etc.

NHS England/ NHS Improvement: Clinical guide for the management of anticoagulant services during the coronavirus pandemic

Last updated 1 April 2020

  • Take the opportunity to review if long-term warfarin therapy is still indicated eg in patients with prior DVT or PE for whom the risk of recurrence is now considered low.
  • Consider if patients taking warfarin are suitable for treatment with a DOAC instead; if a DOAC is unsuitable, could they be switched to LMWH instead? (Note that in view of recognised supply issues with LMWH, these should only be used if there are no other appropriate options).
  • Consider prioritising patients with poor control of INR as this cohort will need the most frequent INR checks. Address non-adherence if this an underlying reason for poor INR control.
  • Consider if patients could be trained to self-test INR in their own homes.
  • As a last resort, for individual patients for whom INR testing is not possible and therefore warfarin cannot be dosed safely, warfarin therapy could be temporarily stopped after weighing the benefit and risk and discussion with the patient. Regular review should be undertaken with a view to restarting warfarin therapy as soon as it is safe to do so. (Note: patients with mechanical heart valves MUST stay on warfarin).

NICE: COVID-19 rapid guideline: acute myocardial injury

Last updated 23 April 2020

  • The purpose of this guideline is to help healthcare professionals who are not cardiology specialists identify and treat acute myocardial injury and its cardiac complications in adults with known or suspected COVID-19 but without known pre-existing cardiovascular disease.
  • Be aware that treatments that may be used in COVID-19, such as azithromycin and hydroxychloroquine, may prolong the QTc interval and lead to arrhythmia (at the time of publication (22 April 2020), azithromycin and hydroxychloroquine can only be used to treat COVID-19 as part of nationally approved randomised controlled trials).

NICE: COVID-19 rapid evidence summary: angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in people with or at risk of COVID-19

Last updated 21 May 2020

  • The purpose of this review is to assess the best available evidence to determine If there is any increased risk of developing COVID-19 due to ACEIs or ARBs and if ACEIs or ARBs can lead to an increased risk of developing more severe symptoms of COVID-19.
  • The review identified 2 retrospective observational studies that met the inclusion criteria; these studies found no increase in risk of developing COVID-19 or more severe disease. However, the studies were of poor quality and subject to bias and confounding.
  • Therefore, conclusions cannot be drawn on whether ACEIs or ARBs increase the risk of developing COVID-19 or developing more severe COVID-19.

Royal Pharmaceutical Society: Guidance for the safe switching of warfarin to direct oral anticoagulants (DOACs) for patients with non-valvular AF and venous thromboembolism (DVT / PE) during the coronavirus pandemic

Last updated 26 March 2020

  • Includes information on how to decide if it is appropriate to switch individual patients to DOACs, choice of DOAC, monitoring etc.
  • Advice on how to manage patients considered unsuitable for a DOAC.
  • Includes a counselling checklist for patients commenced on a DOAC.

British Cardiovascular Society: COVID-19 Clinician’s Resource Hub 

Last updated 18 September 2020

  • Includes a ‘COVID-19 Clinicians Resource Hub’ that is updated with cardiovascular articles pertaining to coronavirus from relevant organisations and publications.

British Cardiovascular Society (BCS) with the British Society for Heart Failure (BSH): Joint statement on ACEi or ARB in relation to COVID-19

Last updated 19 March 2020

  • Both the BCS and the BSH share the view of the European Society of Hypertension and the Renal Association that patients should continue treatment with ACEI and ARB unless specifically advised to stop by their medical team.
  • The BCS and the BSH recommend that patients taking ACEIs or ARBs and presenting unwell with suspected or known COVID-19 infection should be assessed on an individual basis and their medication managed according to established guidance.

British Heart Foundation (patient information): Coronavirus and heart medication

Last updated 21 September 2020

  • There is no evidence that ACEI/ARBs increase the risk of catching coronavirus, or make COVID-19 worse.
  • It’s really important that patients continue to take their cardiac medicines, including ACEI/ARBs, low-dose aspirin and heart transplant medicines as prescribed, even if they catch coronavirus, unless told differently by their doctor.
  • Paracetamol should be used as the first-line treatment for COVID-19 symptoms. If paracetamol doesn’t take down a temperature, taking ibuprofen is unlikely to do any harm.

British Society for Haematology: INR testing for out-patients on warfarin during COVID-19 restrictions

Last updated 26 March 2020

  • Advice for out-patient INR testing during COVID-19 restrictions.
  • Assess whether a DOAC that does not require monitoring can be used instead of warfarin. Note that antiplatelet therapy is not an effective alternative to anticoagulation.
  • Patients who are stably anticoagulated on warfarin with a time-in-therapeutic range of >60% can generally have long INR test intervals of 8 weeks or in some cases longer.
  • Patients in self-isolation because of possible COVID-19 exposure who are stably anticoagulated and would be due a routine test, can usually have the test safely postponed until after the period of isolation

Cardiomyopathy UK: COVID-19 and Cardiomyopathy

Last updated 23 June 2020

Cardiomyopathy UK answers FAQs from patients, including:

  • Should I avoid non-steroidal anti-inflammatory medication like Ibuprofen?
  • I take an ACEI/ARB; should I stop?
  • I am taking immunosuppressant medications (e.g. prednisolone) for the management of my cardiomyopathy, should I stop?
  • Do any other cardiac medications cause harm?

European Society of Cardiology: Position Statement of the European Society of Cardiology Council on Hypertension, ACE-Inhibitors and Angiotensin Receptor Blockers

Last updated 13 March 2020

  • The Council on Hypertension of the European Society of Cardiology have highlighted the lack of evidence supporting harmful effect of ACEI and ARBs in the context of the pandemic COVID-19 outbreak; they strongly recommend that patients should continue treatment with their usual anti-hypertensive therapy.
  • There is evidence from studies in animals suggesting that these medications might be protective against serious lung complications in patients with COVID-19 infection, but to date there is no data in humans.

European Society of Cardiology: ESC Guidance for the Diagnosis and Management of CV Disease during the COVID-19 Pandemic

Last updated 10 June 2020

  • Guidance from the European Society of Cardiology on the diagnosis and management of cardiovascular disease during the COVID-19 pandemic.
  • Has management/treatment pathways for cardiovascular conditions, including STEMI, NSTEMI, cardiogenic shock, heart failure, valvular heart diseases, hypertension, pulmonary embolism and arrhythmias.
  • Also has a section on considerations on the use of anticoagulants in COVID-19 Patients.

European Society of Cardiology: Chloroquine and cardiovascular side effects

  • There has been increased interest in the use of chloroquine and hydroxychloroquine in the context of COVID-19 which is currently under evaluation in trials. There are potential cardiovascular side effects associated with their use.
  • The ESC have summarised output from their meetings and relevant journals.

European Society of Hypertension: Statement of the European Society of Hypertension (ESH) on hypertension, Renin-Angiotensin System (RAS) blockers and COVID-19

Last updated 15 April 2020

  • The currently available data on COVID-19 infections do not a support a differential use of ACEI or ARBs in COVID-19 patients.
  • In COVID-19 patients with severe symptoms or sepsis, ACEI or ARBs and other blood pressure lowering drugs should be used or discontinued on a case-by-case basis, taking into account current guidelines.
  • Further research analysing the continuously increasing data on the impact of hypertension and blood pressure lowering drugs, particularly RAS blockers, on the clinical course of COVID-19 infections is warranted.

Heart UK – The Cholesterol Charity: Information for GP’s and prescribers on how best to manage cholesterol during the coronavirus pandemic

  • Contains advice for healthcare professionals on management of patients with suspected familial hypercholesterolaemia, management of patients experiencing statin side effects and deferral of follow-up cholesterol tests following statin initiation.
  • Patients due to have a follow-up cholesterol test after starting statins who are symptom-free may have to have their appointment deferred depending on service capacity, but they should continue their medication.
  • Patients experiencing side effects should be offered a telephone appointment to review their symptoms, their dose and/or type of statin.
    Patients with suspected familial hypercholesterolaemia should be started on a statin as recommended in NICE CG71; the recommended minimum for most otherwise healthy individuals is atorvastatin 20mg daily.
  • Patients due to have a follow-up cholesterol test following lifestyle changes may need to have their treatment decision delayed. They should, however, continue with lifestyle changes, unless their most recent result met the criteria for familial hypercholesterolaemia screening. These patients would usually be prescribed atorvastatin 20mg daily.
  • Has specific COVID-19 protocols for medications such as PCSK9i, volanesorsen and lomitapide; users must log in to view this, but can sign up to a free professional membership area.

Last updated 27 March 2020

  • There is no evidence from clinical or epidemiological studies that treatment with ACE-I or ARBs might worsen COVID-19 infection.
  • It is vitally important that patients taking ACEI or ARBs to treat high blood pressure continue their usual treatment.
  • The MHRA are working closely with the Commission on Human Medicines and other regulatory bodies and will respond with further advice on this issue, should any new data emerge.
