C. HISTORY AND RISK FACTORS

Element: 4000 Prior Heart Failure
Coding Instruction: Indicate if the patient has been diagnosed with heart failure.
Target Value: Any occurrence between birth and the first generator procedure in this admission
Supporting Definition: Heart Failure

Heart failure is a complex clinical syndrome that results from any structural or functional impairment of
ventricular filling or ejection of blood. The cardinal manifestations of HF are dyspnea and fatigue, which may
limit exercise tolerance, and fluid retention, which may lead to pulmonary and/or splanchnic congestion
and/or peripheral edema. Some patients have exercise intolerance but little evidence of fluid retention,
whereas others complain primarily of edema, dyspnea, or fatigue. Because some patients present without
signs or symptoms of volume overload, the term “heart failure” is preferred over “congestive heart failure.”
There is no single diagnostic test for HF because it is largely a clinical diagnosis based on a careful history and
physical examination.

Brugada syndrome

Polymorphic ventricular tachycardia in the absence

baseline ECG pattern during sinus rhythm showing
right bundle branch block with ST segment
elevation in leads V1 through V3. It can also be
characterized by documentation of ECG patterns
associated with Brugada Syndrome, some of which
may be unmasked when provoked with drugs.
The most common genetic mutations identified for
Brugada syndrome are in a sodium channel gene
(SCN5A). Sodium channel blocking drugs,
therefore, may exacerbate the
electrocardiographic features and clinical
presentation. Brugada syndrome typically presents
before the age of 50 years.

Coding Instruction: Indicate if patient has been on guideline directed medical therapy at least 3 months.
Target Value: The first value between birth and the first generator procedure in this admission
Supporting Definition: Ischemic Guideline Directed Medical Therapy Maximum Dose
For heart failure in the setting of LV systolic dysfunction, this may require individualization but typically
should include the combination of an angiotensin-converting enzyme inhibitor or angiotensin receptor
blocker and beta blocker therapy adjusted to target doses as tolerated, with diuretics adjusted if/as needed
to control fluid retention. In selected patients, the addition of aldosterone antagonists is appropriate. In
addition, in some cases the use of a combination of hydralazine and nitrates may be used instead of an ACE
inhibitor / angiotensin receptor blocker. Patients who are going to receive substantial benefit from medical
treatment alone usually show some clinical improvement during the first 3 to 6 months. Medical therapy is
also assumed to include adequate rate control for tachyarrhythmias, including atrial fibrillation. Therefore, it
is recommended that GDMT be provided for at least 3 months before planned reassessment of LV function to
consider device implantation. If LV function improves to the point where primary prevention indications no
longer apply, then device implantation is not indicated. For stable ischemic heart disease, GDMT should
include aspirin (or a thienopyridine if aspirin is not tolerated), statin therapy, angiotensin-converting enzyme
inhibition (or an angiotensin receptor blocker) and the use of beta-blockers after myocardial infarction.
Therapy for angina/ischemia should include at least 1 of the following medications: beta-blockers, calcium
channel antagonists, or nitrates. Therapy should also be directed at optimizing the treatment of associated
conditions such as diabetes and uncontrolled hypertension.

Element: 4265 Ventricular Tachycardia Reversible Cause
Coding Instruction: Indicate if the ventricular tachycardia was deemed to be a result of a reversible cause. This could include, but
is not limited to, drug abuse or electrolyte imbalance.
Target Value: Any occurrence between birth and the first generator procedure in this admission
Supporting Definition: Ventricular Tachycardia Reversible Cause
Definition of ventricular tachycardia due to a reversible cause.
The most common putative reversible causes of arrest are acute ischemia and electrolyte imbalance. Other
common potential causes to which cardiac arrest is attributed include proarrhythmic effects of
antiarrhythmic drugs (see supporting references).
1) Electrolyte abnormalities, including hypokalemia and hypomagnesemia, facilitate development of VT in
predisposed patients receiving antiarrhythmic agents and other drugs associated with the LQTS. However,
hypokalemia can also result from cardiac arrest and should not otherwise be assumed to be the cause of
cardiac arrest, except under unusual circumstances.(see reference below) Correction of hypokalemia does
not affect inducibility of monomorphic VT occurring after MI. Electrolyte abnormalities should not be
assumed to be the cause of cardiac arrest, except in the presence of drug-induced LQTS.
2) Drugs: In patients who develop polymorphic VT in association with drug-induced QT prolongation,
withdrawal of the offending antiarrhythmic or other agent (e.g., antipsychotic) is usually sufficient to prevent
arrhythmia recurrence. If ventricular function is normal, no therapy beyond drug withdrawal, avoidance of
future drug exposure, and correction of electrolyte abnormalities is necessary. However, if ventricular
function is abnormal, cardiac arrest or syncope should not be attributed solely to antiarrhythmic drugs, and
evaluation and treatment should be similar to patients experiencing such events in the absence of
antiarrhythmic drugs. Occasionally, patients develop monomorphic sustained VT only in the presence of
antiarrhythmic drugs without QT prolongation. In such cases, it may appear that the development of
spontaneous VT is dependent on drug administration. In most patients exhibiting this behavior, the
monomorphic VT is inducible by EP testing in the absence of antiarrhythmic drugs.

Supporting Definition: Myocardial Infarction/Prior MI

Criteria for acute myocardial infarction:
The term acute myocardial infarction (MI) should be used when there is evidence of myocardial necrosis in a
clinical setting consistent with acute myocardial ischemia. Under these conditions any one of the following
criteria meets the diagnosis for MI:
- Detection of a rise and/or fall of cardiac biomarker values [preferably cardiac troponin (cTn) with at least
one value above the 99th percentile upper reference limit (URL) and with at least one of the following:
Symptoms of ischemia.
New or presumed new significant ST-segment-T wave (ST-T) changes or new left bundle branch block (LBBB).
Development of pathological Q waves in the ECG.
Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. Identification
of an intracoronary thrombus by angiography or autopsy.
- Cardiac death with symptoms suggestive of myocardial ischemia and presumed new ischemic ECG changes
or new LBBB, but death occurred before cardiac biomarkers were obtained, or before cardiac biomarker
values would be increased.
- Percutaneous coronary intervention (PCI) related MI is arbitrarily defined by elevation of cTn values (>5 x
99th percentile URL) in patients with normal baseline values (99th percentile URL) or a rise of cTn values
>20% if the baseline values are elevated and are stable or falling. In addition, either (i) symptoms suggestive
of myocardial ischemia or (ii) new ischemic ECG changes or (iii) angiographic findings consistent with a
procedural complication or (iv) imaging demonstration of new loss of viable myocardium or new regional wall
motion abnormality are required.
- Stent thrombosis associated with MI when detected by coronary angiography or autopsy in the setting of
myocardial ischemia and with a rise and/or fall of cardiac biomarker values with at least one value above the
99th percentile URL.
- Coronary artery bypass grafting (CABG) related MI is arbitrarily defined by elevation of cardiac biomarker
values (>10 x 99th percentile URL) in patients with normal baseline cTn values (99th percentile URL). In
addition, either (i) new pathological Q waves or new LBBB, or (ii) angiographic documented new graft or new
native coronary artery occlusion, or (iii) imaging evidence of new loss of viable myocardium or new regional
wall motion abnormality.
Any one of the following criteria meets the diagnosis for prior MI:
- Pathological Q waves with or without symptoms in the absence of non-ischemic causes.
- Imaging evidence of a region of loss of viable myocardium that is thinned and fails to contract, in the
absence of a non-ischemic cause.
- Pathological findings of a prior MI.

C. HISTORY AND RISK FACTORS

Element: 4400 Atrial Fibrillation Classification
Coding Instruction: Indicate the type of atrial fibrillation experienced by the patient.
Target Value: Any occurrence between birth and the first procedure in this admission
Supporting Definition: Atrial Fibrillation Classification

Atrial Fibrillation is a supraventricular tachyarrhythmia with uncoordinated atrial activation and consequently
ineffective atrial contraction.
Electrocardiogram (ECG) characteristics include:
1) irregular R-R intervals (when atrioventricular [AV] conduction is present),
2) absence of distinct repeating P waves, and
3) irregular atrial activity.
Atrial Fibrillation can be further characterized as:
- Paroxysmal AF is defined as AF that terminates spontaneously or with intervention within seven days of
onset. Episodes may recur with variable frequency.
- Persistent AF is defined as AF that fails to self-terminate within seven days. Episodes often require
pharmacologic or electrical cardioversion to restore sinus rhythm.
- Long-standing persistent AF is defined as AF that has lasted for more than 12 month
-Permanent AF is defined as when the patient and clinician make a joint decision to stop further attempts to
restore and/or maintain sinus rhythm. Acceptance of AF represents a therapeutic attitude on the part of the
patient and clinician rather than an inherent pathophysiological attribute of AF. Acceptance of AF may change
as symptoms, efficacy of therapeutic interventions, and patient and clinician preferences evolve.

An ischemic stroke is an acute episode of focal or global neurological dysfunction caused by brain, spinal
cord, or retinal vascular injury as a result of infarction of central nervous system tissue. Hemorrhage may be
a consequence of ischemic stroke. In this situation, the stroke is an ischemic stroke with hemorrhagic
transformation and not a hemorrhagic stroke. A hemorrhagic stroke is defined as an acute episode of focal or
global cerebral or spinal dysfunction caused by intraparenchymal, intraventricular, or subarachnoid
hemorrhage (note: subdural hematomas are intracranial hemorrhagic events and not strokes).

Element: 10200 Discharge Medication Code
Coding Instruction: Indicate the assigned identification number associated with the medications the patient was prescribed upon
discharge.
Note(s):
Discharge medications not required for patients who expired, discharged to "Other acute care hospital", "Left
against medical advice (AMA)" or are receiving Hospice Care.
The medications that should be collected in your application are controlled by a Medication Master file. This
file is maintained by the NCDR and will be made available on the internet for downloading and
importing/updating into your application. Each medication in the Medication Master file is assigned a timing
indicator. This indicator is used to separate procedural medications from medications prescribed at
discharge. The separation of these medications is depicted on the data collection form.

Element: 1000 Participant ID
Coding Instruction: Indicate the participant ID of the submitting facility.
Target Value: N/A
Supporting Definition: Participant ID

Participant ID is a unique number assigned to each database participant by NCDR. A database participant is
defined as one entity that signs a Participation Agreement with the NCDR, submits one data submission file to
the harvest, and receives one report on their data.
Each participant's data if submitted to harvest must be in one data submission file for a quarter. If one
participant keeps their data in more than one file (e.g. at two sites), then the data must be combined into a
single data submission to the system to file for the harvest. If two or more participants share a single
purchased software, and enter cases into one database, then the data must be exported into different data
submission files, one for each participant ID.
Source: NCDR

Element: 1010 Participant Name
Coding Instruction: Indicate the full name of the facility where the procedure was performed.
Note(s):
Values should be full, official hospital names with no abbreviations or variations in spelling.
