Statins for all  ‘treat to target’ e.g. Simvastatin 40mg, then Simvastatin 80mg and then Rosuvustatin 20mg. The mimimum audit target = Cholesterol < 5.0 and LDL <2.5 but an aspirational target of Cholesterol < 4.0 and LDL < 2.0
Adosterone antagonists e.g. spironolactone if symptoms/signs of CCF & LVSDstart within 3-14 days of MI, preferably after the ACE.Monitor U&E’s as per CCF protocol.Halve dose or stop them if hyperkalaemia is a problem.
Refer Cardiology CABG for triple vessel or left main stem diseasePercutaneous approach if single/double vessel diseaseif symptom control fails with GTN prn, betablocker + one other agent.

Beware PPIs negate the benefit of Clopidogrel! So if you have to treat clopidogrel related dyspepsia consider a H2 Blocker (evidence of value still being debated).

ACS management

Arrange immediate admission

High flow oxygen.

iv Tramadol 50mg over 3 mins and iv Maxalon 10mg.

Oral aspirin 300mg – decreases mortality by 25% (ISIS II study).

Oral clopidogrel 300mg stat.

Thrombolysis within 6 to 12hrs of the onset of symptoms – decreases mortality by 25% (ISIS II study).

Beta blockade within 24hrs (ISIS 1 study & NICE 2007).

Early angioplasty (if available) is replacing thrombolysis. Please note the new rules with respect to the duration of clopidogrel use in combination with aspirin vary depending upon the type of MI and the type of stent used.

Drug treatment of ST-elevation myocardial infarction

All patients should have ECG monitoring in an environment where defibrillation and pacing can be performed.

Aspirin 300 mg chewewd should be given to all patients unless there are clear contraindications.

Intramuscular injections should be avoided because of the increased muscle enzyme activity and high risk of bleeding if thrombolytics are administered.

Diamorphine administered intravenously is generally considered to be the drug of first choice unless severe hypotension and/or respiratory depression are present. Metoclopramide is probably the safest anti-emetic for reducing opiate-induced nausea and vomiting.

Oxygen – Ventilation/perfusion abnormalities occur secondary to pulmonary oedema and associated hypoxaemia, and require treatment with oxygen.

Nitrates – Sublingual or intravenous organic nitrates can be used to reduce chest pain provided that the patient is not hypotensive. Particular caution is required to right ventricular infarcts, as venodilatation can precipitate severe hypotension. Nitrates have no effect on mortality.

Beta-adrenoceptor antagonists Early administration of a beta-blocker reduces infarct size and life-threatening arrhythmias. Patients with elevated blood pressure, tachycardia, atrial fibrillation and recurrent chest pain are most likely to benefit, while those with bradycardia, hypotension and conduction problems are most likely to experience adverse effects.

ACE inhibitors ACE inhibitors or the angiotensin-II-receptor antagonist valsartan should also be administered within 24 hours after an ST-elevation infarction or for those with left bundle branch block. Most benefit is due to improvement in left ventricular function.

Acute coronary syndrome without ST elevation

BMJ 2007;334:1265-9

Drug therapy should include:

Aspirin for life– reduces relative risk of further vascular event by 50% (ATC trial, BMJ 2002;324:71-86).

Clopidogrel for up to 12 months post event (reduces risk of vascular event by an additional 20% compared to aspirin alone, (NEJM 2001;345:494-502), but 1% absolute risk increase in bleeding.

BBlockers – to decrease myocardial O2 demand by reducing heart rate and blood pressure and reducing risk of arrhythmias.

Vasodilators (nitrates, calcium channel blockers) for coronary artery vasodilatation and to lower blood pressure. Although neither BBlockers or vasodilators have been shown to reduce the risk of MI or death!

The role of gycoprotein2b/3a receptor inhibitors (eg abciximab) is unclear: theoretically they should be beneficial as they inhibit platelets. However benefit appears only in those who have Percutaneous coronary interventions, not those managed conservatively.

Modify all cardiovascular risk factors (statins, ACE inhibitor for cardio-protection, smoking cessation, screen for diabetes, obesity reduction, increase physical activity).

 

Thrombolysis

For patients with ST-segment elevation, thrombolysis results in reperfusion in 50-70% of those treated.

This is translated into improved left ventricular function, and reduced arrhythmias, cardiogenic shock and mortality. The best results occur if percutaneous coronary intervention is performed soon after drug administration. The greatest benefit is achieved with early thrombolysis, especially if given within 4 hours of the onset of chest pain.

Adverse effects and contraindications Bleeding, symptomatic hypotension and allergic reactions are the most common and serious reactions associated with streptokinase therapy. However, hypertension can be associated with reperfusion, due to successful thrombolysis and recanalisation. Allergic reactions which include fever, rashes, serum sickness, polyneuropathy and (rarely) anaphylaxis occur in about 12% of patients treated. These reactions are rarely seen with other thrombolytic agents, e.g. alteplase, and severe reactions usually occur on re-exposure.

Any condition which increases the risk of bleeding represents a relative or absolute contraindication to the use of streptokinase and other thrombolytic agents. A previous history of an allergic reaction to streptokinase is an absolute contraindication. Great care is also required when giving thrombolytic drugs to patients who are already receiving anticoagulants and antiplatelet drugs.

Thrombolytics
Streptokinase Inexpensive AntigenicOccasional allergic reactionHypotensionNeed heparin
Anistreplase Rapid effect with prolonged actionAntigenic Occasional allergic reactionModerately expensive
Alteplase Short half-lifeNon-antigenicHighly clot selectiveVery expensive

Clopidogrel

All patients following an acute coronary syndrome or who have undergone percutaneous coronary intervention should receive clopidogrel. A loading dose of 300 mg followed by a maintenance dose of 75 mg was the regimen used in the outcome trials. This should be combined with 75 mg of aspirin. To date there is no evidence of clinical benefit beyond 1 year for the combination.

 

NSTEMI  and unstable angina

differs from that of STEMI in a number of key areas:

Thrombolytic therapy is of no proven value.

Rate-limiting calcium-channel blockers such as verapamil or diltiazem are useful adjuvants to analgesics, nitrates and beta-blockers.

HMG CoA reductase inhibitors have been shown to reduce mortality and recurrent myocardial infarction when administered in the acute setting.

Glycoprotein-llb/llla antagonists have been shown to protect patients with NSTEMI and unstable angina from death and non-fatal myocardial infarction during the acute phase of their presentation and for 24 hour following intervention.

Unfractionated and low-molecular-weight heparin reduces the risk of further myocardial infarction, often combined with antiplatelet drugs.

Ticagrelor

NICE Ticagrelor Guidance via NELM Oct 2011

 

Drug therapy in CVD and post MI
ACE inhibitor ACE inhibitors should continue for life even in the absence of LVF/LVSD.ARBs if allergy/intolerance of ACE
Aspirin 300mg in suspected ACS then 75mg od indefinately.A PPI should be given to those with a history of dyspepsia. Those with a history of aspirin induced gastrointestinal haemorrhage should be considered for aspirin therapy with full dose PPI protection. Only those truly intolerant to aspirin may be considered for monotherapy with clopidogrel.For those on warfarin for some other reason (eg. recurrent DVT) and who are at low risk of bleeding consider aspirin and warfarin with a PPI.
Clopidogrel Patients given aspirin and clopidogrel within the first 24 hrs post MI should continue to take both for 1 month,then aspirin alone.Those with non-ST elevation acute coronary syndrome should be given aspirin with clopidogrel for 12m.
B-Blocker BBlockers reduce mortality after MI & in heart failure & are 1st line drug in angina.BBlockers are no longer the drug of choice for most people with hypertension.
Statins give to all post-MI regardless of their cholesterol level

 

Cardiac rehabilitation

http://www.cardiacrehabilitation.org.uk/

British Heart Foundation Cardiac Rehabilitation Factfile

Aims is to restore patient to the best possible function after ACS and to minimise risk of recurrence.

Cardiac rehabilitation improves risk, morbidity, mortality and psychosocial outcome.

May reduce mortality by 20-25%.

Measuring Blood Pressure

Patient sat comfortably, rested, no recent nicotine or caffeine. arm fully exposed and resting in slight flexion supported on desk with brachial artery at heart level.

Choose appropriate size cuff for size of arm. Wrap neatly and tightly round arm with lower end approx 2-3 cm above antecubital fossa.

Ensure dial visible and set to zero. Tighten air valve palpate radial artery and inflate quickly till pressure obliterates radial/brachial pulse. Let down pressure and note approx systolic pressure when pulse returns.

Place stethoscope over radial artery. Reinflate cuff to 30mm above this value. Release pressure steadily approx 2-3 mm per second.

Note the appearance  of audible sounds 1st Korotoff = systolic pressure.

Note complete disappearance  (not muffling) of audible sounds  2nd Korotoff sound = diastolic pressure

Heart failure annual review

Check NYHA classification, BMI, smoking status/cessation advice, alcohol intake, BP, Cr&Es, fasting lipids (cholesterol & LDL), fasting blood sugar etc within the last 12 months.

patient pathway –

Patients, as a result of remembering their annual review date or having a reminder on their prescription will ring to book their annual review. The reception team will book a fasting bloods & BP appointment with one of the HCAs.

The HCAs will review the patients comorbidities using the SystmOne chronic disease icons page (checking for COPD, Asthma, HT, IHD/TIA/CVA) to decide the tests they have to perform. They will also arrange a 20 minute review with a Practice Nurse but a 30 minute appointment if they have asthma, COPD or a history of MI, angina, TIA or stroke.

The Practice nurses on completing the annual review, where no action is deemed to be necessary, will also document and inform the patient of their next planned review date and task the appropriate GP to code the medication review and reauthorise the prescriptions. Patients requiring further assessment or a change in medication will be referred to the GP.

Dyspepsia on aspirin
In patients experiencing dyspepsia, try a switch to enteric coated aspirin
If not, then add Omeprazole 20mg if the symptoms are not settling.
Those patients still experiencing dyspepsia on aspirin plus PPI, should be considered for Clopidogrel, and the PPI should be discontinued, except in high risk GI patients, where long term PPI cover should be considered. Persisting dyspepsia on Clopidogrel should require investigation.Even in patients with history of peptic disease can be treated with PPI plus aspirin.

aspirin plus warfarin

MeReC Extra No. 28, 2007

A systematic review looked at whether aspirin added to warfarin in those at high risk of arterial thromboembolism (defined as MI, unstable angina requiring hospitalisation, CVA, TIA, systemic embolism) (Arch Int Med 2007;167:117-24).

Subgroup analysis showed the most significant advantage was in those with mechanical heart valves, who had a significant reduction in thrombotic events with a risk of GI bleed no greater than the other subgroups (ie. higher than with warfarin alone, but not higher than the overall risk for those on warfarin and aspirin).

American Heart Association recommends that aspirin (75mg) should be added to those on warfarin with mechanical heart valves.

SIGN 97 2007 CVD risk estimation

For adults 30-75 years (NB Vasc Screening 40-75) with the following:

Hypertension, Smoking, FH premature CHD, clinical signs dyslipidaemia, Diabetes (in fact treat as 2ndry or use UKPDS)

For hypertensive patients on treatment, pretreatment levels should be used where possible when assessing risk.

Clinical judgement needs to be used for patients who have been well controlled for years and for whom a pre-treatment level is not available; however, if using treatment BP levels, bear in mind that the patient’s CVD risk is probably higher than expected.

Do not asses CVD risk already have established CVD, or Diabetes and over 40, FHC – treat as high risk anyway.

Lipid guidelines for primary prevention
Target Population aged 40-74 no history of cardiovascular disease no diabetes Over 75s may be at high CV risk, especially if they smoke or have high BP, but most data on CV risk, including the Framingham data, include very few people >74y, and most risk calculators stop at 74y.NICE recommends balancing comorbidities, benefits and risks and treating according to clinical judgement,
Perform ‘prior risk assessment’ guestimate of  CVD risk when some of the data required for a formal risk assessment is absentallows those at highest risk to be identified and targeted for a full formal risk assessment with up to date data Perform formal CVD risk assessment if ‘prior risk assessment’ >20%/10yUse Framingham 1991 risk equation (including average of at least 2 systolic BPs, and data on LVH).
Adjust for ethnicity South Asian origin multiply CVD risk by 1.4
Adjust for FH Family history of coronary heart diseaseMale first degree relative under 55 with CHDOR Female first degree relative under 65 with CHD Multiply risk by 1.5 if one relative affected (ie. act if 10y CVD risk =13.3%)Multiply risk by 2 if 2 or more relatives affected (ie. act if 10y CVD risk = 10%).
Consider false negatives with CVD risk score below 20% but in whom the risk estimation may be falsely low:Low socioeconomic statusOn antihypertensives or lipid lowering drugsBMI >40Recently stopped smokingChronic condition that increases CVD risk (CKD, SLE, HIV, on antipsychotics). Use clinical judgement to determine whether to treat these individuals as high risk.

Starting and monitering statins

Simvastatin 40mg is advocated for first line use because of cost and efficacy.

Effective for lowering LDL cholesterol, but can increase HDL cholesterol (especially rosuvastatin) and lower triglycerides.

Other agents will be needed in some patients when a statin alone is insufficient for reducing LDL cholesterol, when they are intolerant of a statin, or when the triglyceride levels are very high.

Most authorities state the benefits of statin therapy in large populations greatly outweigh the adverse effects.

The main adverse effects liver damage,  rhabdomyolysis and peripheral neuropathy develops.

These adverse effects are more common when statins are combined with fibrates (especially gemfibrozil).

No need to monitor patients on 10 mg simvastatin.

All other patients should have baseline liver function tests which should be repeated 1-3 months after treatment is initiated. Thereafter, LFTs should be checked at intervals of 6 months for the first year of treatment, and then annually.

Only check CK   if patient develops  muscle pain/tenderness/weakness.

Start with e.g. Simvastatin 40mg and warn the patient about common side or serious side effects e.g. myalgia.

Check fasting lipids and ALT at 4 weeks. Uptitrate the dose if not at target  and repeat in another 4 weeks.

If that fails to achieve target try titrating to target using Atorvastatin 20mg then  40mg, then  80mg)

Stop statin if ALT x3 upper limit of normal or if has suspected myopathy with CK> 5 x normal.

If they have myalgia with a normal CK then try switching to Simvastatin 20mg or Pravastatin 40mg as an alternative.

If that fails consider Ezetimibe, Ciprofibrate or an anion exchange resin.

remember less than half of patients on treatment will reach their target  – don’t pursue blindly

 

Clinical scenario Use
Post ACS HIS Atorvostatin 80mg Rosuvostatin 20/40mg
Secondary Prevention S 40mg titrating up to S80 or equivalentAtorvostatin 10 -20mgif CI try lower dose of alternative eg pravastatin or atorvostatin 10mg and titrate up
