In addition to the prediction of cardiovascular risk, ambulatory blood-pressure monitoring, when used in conjunction with clinic blood-pressure assessments, is of potential value in a variety of other clinical conditions. Some of these conditions are:

Clinical Predictors of Increased Perioperative Cardiovascular Risk (Myocardial Infarction, Heart Failure, Death)
Major
Myocarditis may present with a wide range of symptoms, ranging from mild dyspnea or chest pain that resolves without specific therapy to cardiogenic shock and death. Dilated cardiomyopathy with chronic heart failure is the major long-term sequela of myocarditis. Most often, myocarditis results from common viral infections; less commonly, specific forms of myocarditis may result from other pathogens, toxic or hypersensitivity drug reactions, giant-cell myocarditis, or sarcoidosis.

Sokolow-Lyon index:
There are two criteria with these widely used indices:
* Sum of S wave in V1 and R wave in V5 or V6 >/= 3.5 mV (35 mm)
and/or
* R wave in aVL >/= 1.1 mV (11 mm)

The TIMI risk score, based upon data from 15,000 patients with an ST segment elevation myocardial infarction eligible for fibrinolytic therapy, is a simple arithmetic sum of eight independent predictors of mortality.

Indications
Recurrent syncope or single syncopal episode accompanied by physical injury or motor vehicle crash or occurring in a high-risk setting (for example, pilot, surgeon, commercial vehicle driver) and no evidence of structural cardiovascular disease; or presence of structural cardiovascular disease, but other causes of syncope ruled out by diagnostic testing
Syncope induced by or associated with exercise

The Wells Clinical Prediction Rule is a diagnostic tool used during review of systems to identify possible pulmonary embolism (PE) and deep vein thrombosis (DVT). Continue reading “Wells Clinical Prediction Rule for Pulmonary Embolism and Deep Venous Thrombosis”
Diagnostic Criteria for Heparin-Induced Thrombocytopenia (HIT)
Cardiac causes
Structural cardiac or cardiopulmonary disease (aortic stenosis, mitral stenosis, pulmonary stenosis, left atrial myxoma, aortic dissection, acute myocardial infarction, cardiac tamponade, pulmonary embolism, obstructive cardiomyopathy)
Cardiac arrhythmias (tachyarrhythmias, bradyarrhythmias)
Neurally mediated syncopal syndrome (includes neurocardiogenic or vasovagal syncope, carotid sinus syncope, and situational syncope)
Orthostatic (or postural) hypotension
Diagnostic criteria include the following:
