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

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:

Criteria for acute, evolving or recent MI
Either one of the following criteria satisfies the diagnosis for an acute, evolving or recent MI:
1) Typical rise and gradual fall (troponin) or more rapid rise and fall (CK-MB) of biochemical markers of myocardial necrosis with at least one of the following:

The classification is based on the average of two or more properly measured, seated blood pressure readings on each of two or more office visits.
Continue reading “JNC-VII Classification and management of blood pressure for adults”
This classification equates with that of the European Society of Hypertension (ESH) and that of World Health Organization/ International Society of Hypertension (WHO/ISH), and is based on clinic blood pressure values. If systolic blood pressure and diastolic blood pressure fall into different categories, the higher value should be taken for classification.
