Table 1. Recommendations for Secondary Prevention of IVD
Lifestyle with Medication | |
---|---|
Blood Pressure Control |
Blood pressure (BP) goal :
For patients not at target :
|
Tobacco Treatment |
Goal : Complete cessation. Ask all patients about tobacco use. Tobacco use status should be documented in the medical record and re-assessed at every patient encounter [IA] . Advise all tobacco users seriously to consider making a quit attempt using a clear and personalized message [IA]. Advice as brief as three minutes is effective [IA] . Assess all tobacco users' willingness to make a quit attempt . If not ready to quit, offer motivational intervention using the 5 "R's" – relevance, risks, rewards, roadblocks, repetition [IA] . Assist those ready to make a quit attempt . Refer patients interested in quitting within 30 days to a Tobacco Treatment specialist or other appropriate tobacco treatment program [IA] . Alternatively healthcare providers can directly provide the following treatment:
Arrange follow-up either with phone call or office visit [IA] . Subsequent visits :
|
Lipid Management |
Full lipid panel (total cholesterol, low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], and triglycerides): Obtain for all patients [IA] . Lifestyle modification : recommend regular exercise if no contraindication, assess and strongly recommend lowering caloric intake from saturated fat to <7%, and recommend lowering the percentage of calories from trans fats [IA] . Secondary causes of lipid disorders : assess for and optimize if identified. Statin (if no contraindication) :
Other/additional medications : Consider in patients who are completely statin intolerant or are not able to tolerate the recommended statin intensity. |
Diabetes Management |
Glycemic control :
Blood pressure goal : SBP ≤140 mm Hg [IB] . DBP <90 per Joint National Committee (JNC) 8 Panel, possibly better if <80 per American Diabetes Association. Statin therapy : at least use moderate-intensity statin therapy if no contraindication. (See "Statin" in Lipid Management section above for further details.) Tobacco use : Check status at every encounter and at minimum annually. Recommend nonsmoking, educate, encourage cessation [IC] . |
Depression Screening |
Screen for depression : is reasonable in patients with IVD. Treat depression or refer when indicated [IIB] . Initial screening for patients with IHD can be performed by use of the standard Patient Health Questionnaire-2 (PHQ-2) depression screening tool: During the past month, have you been bothered by:
If the patient responds "yes" to either question, move to the more detailed PHQ-9. |
Medication | |
Antiplatelet Agents and Anticoagulants |
For established IHD: antiplatelet . Prescribe aspirin at a dose of 81 mg daily [IA]. In patients intolerant to aspirin, prescribe clopidogrel at a dose of 75 mg daily (or ticlopidine after consulting with cardiology) indefinitely [IA] . For recent acute coronary syndromes treated medically without angioplasty: antiplatelet. In addition to aspirin, add clopidogrel at a dose of 75 mg daily for at least 1 month [IA] and ideally up to 1 year post-event. Following coronary stent placement: antiplatelet . Prescribe aspirin at a dose of 81 mg as above [IA] . The duration of therapy of additional antiplatelet is usually determined by the cardiologist.
Following non-cardioembolic stroke :
In patients with persistent or paroxysmal non-valvular atrial fibrillation : an anticoagulant is generally recommended over an antiplatelet.
|
β blockers in IHD |
Beneficial : Start and continue oral β blocker therapy indefinitely (unless contraindicated) in all patients who either have had a ST-elevated myocardial infarction (STEMI) [IA] or have unstable angina (UA)/non-ST-elevated myocardial infarction (NSTEMI) with left ventricular (LV) dysfunction [IB] . Reasonable : Prescribe β blockers for low-risk patients (i.e., normal LV function, revascularized, no high-risk features) recovering from UA/NSTEMI in the absence of absolute contraindications [IIB] . |
Renin-angiotensin-aldosterone System Blockers in IHD |
ACE inhibitors : prescribe unless contraindicated in all patients with IHD who also have hypertension, diabetes mellitus, LV ejection fraction 40% or less, or chronic kidney disease. [IA] . An ACE inhibitor is an appropriate choice for other patients with IHD [IIB] . ARBs : prescribe to the above patients if they are intolerant of ACE inhibitors [IA] . Aldosterone blockade : prescribe for patients who are post-myocardial infarction and are:
|
Non-steroidal Anti-inflammatory Drug (NSAID) for Pain Control |
At admission for acute coronary syndrome : discontinue all cyclooxygenase-2 (COX-2) inhibitors and NSAIDs, EXCEPT aspirin as above [ID] . NSAIDs increase IHD events and alternative should be sought. In patients with IHD requiring analgesia : a stepped-care approach to treatment should be used [ID] (see text in the original guideline document). If the initial stepped approach is insufficient , using nonselective NSAIDs (preferably naproxen) is reasonable [IID] . |
Immunizations |
Influenza vaccination : annually (inactivated, injectable) [IB] . Pneumococcal vaccination (polysaccharide vaccine): initially when diagnosed with IVD and if initial vaccination occurred before age 65 years, revaccination after age 65 and 5 years have passed since initial vaccination [IB] . |
Lifestyle | |
Physical Activity |
Assess risk associated with exercise (e.g., need for cardiopulmonary monitoring) using a physical activity history and/or exercise test to guide the exercise recommendation [IB] . Encourage :
For those with recent acute coronary syndromes or recent revascularization : Recommend medically supervised cardiac rehabilitation programs [IA] . |
Weight Management |
Each visit : Assess body mass index (BMI) and encourage weight maintenance/reduction through an appropriate balance of physical activity, nutrition/caloric intake, and formal behavioral programs when indicated to achieve and maintain a body mass index between 18.5 and 24.9 kg/m 2 [IC] . For patients >65 years, a BMI of <22 kg/m 2 may be below normal and a BMI of 25 kg/m 2 to 30 kg/m 2 may be acceptable [IID] . Initiate treatment for non-elderly patient: If overweight (BMI 25.00 to 29.99) or obese (BMI ≥30.00), initiate lifestyle change through diet and exercise [IC] . Weight loss goals : Initial goal of weight loss strategy should be to reduce body weight 5% to 10% from baseline over a span of 6 months. With success further weight loss can be attempted if indicated through further assessment [ID] . |
Nutrition |
Promote :
|
Surgery | |
Symptomatic Carotid Artery Disease |
Carotid endarterectomy :
Carotid stenting : An alternative to carotid endarterectomy when patients at high risk for surgery or in specific circumstances (e.g., high carotid bifurcation, extensive radiation induced stenosis, prior carotid intervention). The perioperative morbidity and mortality of carotid stenting should be less than 6% [IIA] . Other therapies : All patients with carotid disease after stroke should be on optimal medical therapy and have appropriate lifestyle modifications, whether or not an intervention is performed [IA] . |

Methodology
Methods Used to Collect/Select the Evidence
- Hand-searches of Published Literature (Secondary Sources)
Description of Methods Used to Collect/Select the Evidence
The overview of secondary prevention recommendations was assembled from existing guidelines. The University of Michigan Health System (UMHS) has already developed guidelines addressing many of the components of secondary prevention (i.e., tobacco cessation, hypertension, lipid management, diabetes mellitus, obesity [physical activity, weight management, nutrition], and immunizations). The review began with the UMHS guidelines and the national guidelines referenced in them. The review expanded to other relevant guidelines of the American College of Cardiology (ACC), the American Heart Association (AHA), and the American Stroke Association (ASA). Then evidence from relevant guidelines referenced in those guidelines and other relevant national guidelines known to the authors were added. The search focused on guidelines published from January 2000 through July 2008 to produce the 2009 version of this guideline. This 2014 update included similar searches for evidence in more current guidelines over the period from August 2008 through December 2013. The section of this guideline on “Related National Guidelines” lists twenty current national guidelines on which this overview is based.
The search was supplemented with very recent clinical trials known to expert members of the panel. Negative trials were specifically sought.

Rating Scheme for the Strength of the Recommendations
Strength of Recommendation
- Generally should be performed
- May be reasonable to perform
- Generally should not be performed
Cost Analysis
Adding a proton pump inhibitor (PPI) to antiplatelet therapy is cost effective for individuals at increased risk for gastrointestinal (GI) bleeding, but is not cost effective in patients with average bleeding risk.
Method of Guideline Validation
- Internal Peer Review
Description of Method of Guideline Validation
Drafts of this guideline were reviewed in clinical conferences and by distribution for comment within departments and divisions of the University of Michigan Medical School to which the content is most relevant: Cardiovascular Medicine, Family Medicine, General Internal Medicine, Neurology and the Committee of Pharmacy and Therapeutics. The final version was endorsed by the Clinical Practice Committee of the University of Michigan Faculty Group Practice and the Executive Committee for Clinical Affairs of the University of Michigan Hospitals and Health Centers.
Evidence Supporting the Recommendations
Type of Evidence Supporting the Recommendations
The type of evidence supporting the recommendations is specifically stated select recommendations (see the “Major Recommendations” field).
Conclusions were based on prospective randomized controlled trials (RCTs) if available, to the exclusion of other data; if RCTs were not available, observational studies were admitted to consideration. If no such data were available for a given link in the problem formulation, expert opinion was used to estimate effect size.
Benefits/Harms of Implementing the Guideline Recommendations
Potential Benefits
- Reduced risk of subsequent cardiac events and mortality
- Prevention of coronary artery disease and other vascular disease
Potential Harms
- The U.S. Food and Drug Administration (FDA) issued an alert regarding serious neuropsychiatric symptoms occurring in patients taking varenicline; however, it still continues to be considered first line therapy. Clinicians should elicit information on their patients’ psychiatric history and monitor them for changes in mood or behavior on therapy.
- Antiplatelet and anticoagulant therapy
- Prasugrel is not recommended in patients older than 75 years of age except in those patients with diabetes or prior history of myocardial infarction (MI). Prasugrel has not been studied in patients undergoing elective percutaneous coronary intervention (PCI).
- Ticagrelor is associated with higher rates of transient dyspnea and bradycardia. Ticagrelor has not been studied in elective PCI.
- The combination of aspirin and clopidogrel increases the risk of bleeding without reducing the risk of stroke, therefore, the long-term use of dual antiplatelet therapy cannot be recommended for non-cardioembolic stroke.
- Anticoagulation with warfarin or one of the three new anticoagulants increases the risk of bleeding without reducing the risk of ischemic events in patients with stroke due to cardioemboli.
- Antiplatelet therapy reduces risk of cardiovascular events, but increases risk for gastrointestinal (GI) tract bleeding.
- There are limited data on the safety of “triple therapy” with aspirin, clopidogrel, and warfarin, leading to significant concerns about the risk of bleeding.
- In the acute setting, the routine use of intravenous (IV) β blockers for all patients is not recommended, as it may be harmful to administer them to those with contraindications to beta blockade, signs of heart failure or low output state, or other risk factors for cardiogenic shock.
- Serum potassium should be monitored closely during treatment with aldosterone blockade. Although uncommon, life-threatening hyperkalemia can occur due to the combination of aldosterone inhibition, reduced aldosterone secretion associated with angiotensin-converting enzyme (ACE) inhibitor therapy, and a progressive decline in renal perfusion due to heart failure.
- The selective cyclooxygenase-2 (COX-2) inhibitors and other nonselective non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with increased cardiovascular risk. The risk of cardiovascular events is proportional to COX-2 selectivity.
- Of note, some herbal remedies can have cardiotoxic properties, some may lower serum potassium, and some may interact with cardiovascular drugs.
- Patient selection for carotid revascularization is important as perioperative risks can negate potential benefits from the procedure.
Contraindications
Contraindications
- Nicotine transdermal formulations are contraindicated in patients with arrhythmias, worsening angina, severe angina, and within 2 weeks of myocardial infarction. Use nicotine supplements with caution in patients with ischemic heart disease (IHD).
- Prasugrel is contraindicated in patients with a prior history of stroke or transient ischemic attack (TIA).
- The new oral anticoagulants are contraindicated for patients with renal failure and caution should be used in patients with renal impairment.
- Influenza vaccine is contraindicated in patients with severe egg allergy or previous allergy/anaphylaxis to influenza vaccine and cautioned with previous Guillain-Barré syndrome.
- Ephedra, oleander, or other herbal/botanicals have well-defined contraindications to cardiovascular drug and or cardiovascular disease (CVD) conditions.
- Anticoagulation with any agent is not recommended immediately after an acute stroke due to the risk of hemorrhagic transformation.
- With the exception of aspirin, all non-steroidal anti-inflammatory drugs (NSAIDS) and cyclooxygenase-2 (COX-2) inhibitors should be discontinued immediately at the time of an acute coronary syndrome presentation.
- Bile acid sequestrants (resins) are relatively contraindicated in patients with triglycerides ≥200 mg/dL.
- Contraindications to β blockers include signs of acute heart failure, evidence of a low output state and increased risk for cardiogenic shock.
