    …Comprehensive Care Towards Wellness

    You know the statistics…cardiovascular disease, annually accounts for more than 50% of all deaths, 19% of total disability claimants, and 21% of total healthcare costs. In the next decade, the population with the highest prevalence of cardiovascular disease is expected to increase by 35%.

    Women or men at risk for cardiovascular events are identified based on the presence of at least one of the following criteria:

    1. Coronary Artery Disease (CAD), including previous myocardial infarction (MI), coronary artery bypass surgery (CABG), percutaneous coronary intervention (PCI), unstable angina, or stable angina (with an angiogram demonstrating >50% stenosis in at least 1 major artery or a positive stress test);
    2. Evidence of Peripheral Vascular Disease (PAD), including a history of intermittent claudication, or documented decrease in pulses or bruits supported by an ankle-brachial index (ABI) <0.9 or duplex ultrasound diagnosis (demonstrating >50% stenosis in at least 1 major artery);
    3. History of Cerebrovascular Disease (CVD), including a history of stroke or transient ischemic attack (TIA);
    4. Diabetic patients with at least one risk factor for CAD, including hypertension (systolic blood pressure >160 mmHg or diastolic blood pressure >90 mmHg or on treatment), total cholesterol >5.2 mmol/L, HDL cholesterol <0.9 mmol/L, current cigarette smoker, known microalbuminuria, or any evidence of previous vascular disease; or,
    5. Three or more Coronary risk factors being present.

    Add to this the rise in diabetes and the increasing need for secondary, as well as primary prevention management, and more of your patients than ever before, will need efficient access to quality care and lifestyle education programs.

    Comprehensive Assessment, Prevention and Rehabilitation Services at One Clinic

    For more than a decade, KMH has been a leading provider of cardiology diagnostic tests and has developed the International Heart Institute (IHI), directed by Arvinder Grover, M.D., F.R.C.P., (C), F.A.C.C.. This High Risk Clinic is specifically designed for patients who either suffer from Coronary Artery Disease or who are not yet diagnosed with cardiac disease but have multiple cardiac risk factors, placing them at risk for vascular events. Referred patients will be genuinely motivated to make the lifestyle changes necessary to gain control of their cardiac risk profile.

    Through a multi-disciplinary approach, Cardiologists and Internal Medicine Specialists, as well as other health care professionals, help empower your patients with knowledge about their health risks and provide non-pharmacological and pharmacological strategies to implement day-to-day.

    ED Heart Disease Predictor

    Erectile Dysfunction Predictor of Coronary Heart Disease in Men Referred for Stress Testing

    Recent research results suggest that Erectile Dysfunction (ED) is associated with markers of adverse cardiovascular prognosis and is a strong, independent pretest predictor of severe coronary heart disease. It is also a valuable stratifier of high cardiovascular risk in men, especially those over age 50.

    Erectile dysfunction has been demonstrated to share common risk factors with coronary artery disease that includes diabetes, hypertension, smoking, and hyperlipidemia. The prevalence of ED in cardiovascular patients is higher than in the general population; in men presenting with ED, 56% were found to have a positive stress test (stress ECG, stress Cardiolite and/or stress ventricular function study) demonstrating myocardial perfusion and functional impairment. Conversely, in men with a history of heart disease or previous myocardial infarction, the incidence of sexual dysfunction ranges from 40 – 64%.*

    It has been postulated in the medical literature that penile arteries are relatively small in comparison with the coronary arteries; they may be more prone to cause ED with even comparatively small amounts of atherosclerosis. This early warning sign is also a barometer of global vascular impairment that usually precedes the onset of overt coronary artery disease. Regardless, men over the age of 50, who present with ED should be evaluated for cardiovascular disease, especially men with concomitant risk factors such as smoking, hypertension, diabetes mellitus, hypercholesterolemia and obesity.

    The guidelines now available for the assessment and management of ED in the cardiovascular patient stratifies men into low, medium or high risk depending on the activity of their cardiovascular disease. A comprehensive cardiac evaluation and consultation should be performed prior to treatment for erectile dysfunction and/or resumption of sexual activity as the pharmalogical prescriptions for treating coronary artery disease should not be combined with organic nitrates (which are often given for ED).

    Referral Procedures – Stop ED Medications for at least 24 hours prior to Diagnostic Testing

    For patients referred for stress testing, erectile dysfunction medication should be stopped prior to stress testing. Nitrates are a very effective first line treatment for stress induced ischemia. Since recent intake of erectile dysfunction medications is an absolute contraindication to nitrates, performing stress tests on patients who have recently taken these medications will unnecessarily increase the risk of stress testing. (There is minimal risk to patients not taking such medication). For short-acting medications, such as Viagra, patients should not take them for 24 hours prior to the test. For longer acting preparations, such as Cialis, patients should be off the medication for 48 hours prior to the test.

    Use the KMH Cardiology Requisition Form. Your office or your patient may call to book an appointment (905-855-1860 or 1-877-564-5227) at any of the eight KMH Cardiology & Diagnostic Centres in south-central Ontario. Patients may visit www.kmhlabs.com for the location most convenient.
