Diabetic Retinopathy And E.c.g. Changes Pahda S P, Manhas A S - Indian J Ophthalmol

Diabetes mellitus, the prevalence of which is on the increase in all mechanised societies, is still a challenge to the medical science. It is well known that inspite of an adequate clinical control of the disease, an insidious progress of the degenerative vascular changes continues. With better therapeutics, the life span of a diabetic has appreciably increased and so have the accompanying complications. There is an increasing interest in the complications affecting the eye (retinopathy) not because they are responsible for the blindness but because they help us to assess the morbid state of various organs particularly the kidneys and the heart. One hundred and fifty diabetics with different grades of retinopathy and unselected regarding the age, sex, age of onset, type of therapy and level of control of the disease have been studied for abnormal E.C.G. changes. All the cases had complete ocular examination including slit lamp examination and detailed fundus examination after full mydriasis, with direct ophthalmoscope. The retinopathy was classified according to Burditt et al.1 into `Simple' and `Malignant' retinopathy. The patients were classified according to the changes present in more severely affected eye. Electrocardiogram for all leads was recorded in every case and abnormalities noted. A matching group of fifty diabetics without any ophthalmoscope changes in the retina also had their E.C.G. recorded and abnormalities noted. Distribution of the retinopathy sample according to age, sex and duration of the diabetes [Table - 1] reveals 86 males and 64 females ranging from 26 years to 73 years in age and from 3 years to 24 years in duration of diabetes. Maximum number of patients (97 cases) were in the age group 41-60 years and 74 percent of the sample (111 cases) h Continue reading >>

Major Abnormalities On Ecg Tied To Cvd Risk In Type 1 Diabetes

Major abnormalities on ECG tied to CVD risk in type 1 diabetes Soliman EZ, et al. Diabetes Care. 2017;doi:10.2337/dc16-2050. Major abnormalities on an electrocardiogram may be useful for predicting the development of cardiovascular disease in adults with type 1 diabetes, according to findings published in Diabetes Care. Elsayed Z. Soliman, MD, of the Epidemiological Cardiology Research Center, department of epidemiology and prevention and department of medicine, section on cardiology, at Wake Forest School of Medicine in Winston-Salem, North Carolina, and colleagues evaluated data from the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study on 1,306 adults (mean age, 35.5 years) with type 1 diabetes to determine the prevalence and incidence of ECG abnormalities with the development of CVD . Follow-up was a median of 19 years. The Minnesota Code ECG classification was used to define ECG abnormalities as major, minor or none. First occurrence of myocardial infarction, stroke, confirmed angina, coronary artery revascularization, congestive heart failure or death from any CVD were used to define CVD events. Through follow-up, 11.9% of participants developed CVD events for an incidence of 46.8 per 10,000 person-years. Most events were nonfatal (n = 148) and included 34 participants with clinical MI, 38 with silent MI, 16 with confirmed angina pectoris, 39 with coronary revascularization, three with congestive heart failure and 18 with stroke. Seven events were fatal and included two participants with sudden death. The risk for a CVD event was increased more than 2.5 times with the presence of any major ECG abnormality compared with no abnormality/normal ECG (HR = 2.67; 95% CI, 1.62-4.4) or no major abnormality Continue reading >>

Prognostic Value Of Ecg In Diabetes Mellitus: The Danger Of Knowing Too Much

Rev Esp Cardiol. 2007;60:1015-7 - Vol. 60 Num.10 Prognostic Value of ECG in Diabetes Mellitus: The Danger of Knowing Too Much a Servicio de Cardiologa, Hospital Virgen de la Salud, Toledo, Spain Type 2 diabetes mellitus (DM2) is a disease with an increasingly high prevalence leading to a rise in cardiovascular risk. Around 75% of patients with DM2 die with some sort of cardiovascular disorder, such as myocardial infarction or stroke. Indeed, the future increase in DM2, as a consequence of the rise in obesity with which DM2 is pathophysiologically associated, will be one of the main causes of the increase in cardiovascular death and disease in both developed and developing countries over the coming decades.1 Furthermore, the presence of diabetes largely determines the treatment pattern of major cardiovascular diseases,2 thus enhancing its role in cardiovascular disorders. Since Haffner et al3 noted that the cardiovascular risk in a patient with DM2 was similar to that of a patient without diabetes but who had suffered a myocardial infarction, it has been established that DM2 is associated with an equivalent risk to that of coronary heart disease (>=2% annually). In fact, the AHA4 and the ESC5 both consider DM2 as an equivalent of coronary heart disease and have recommended similar strategies and aims to those of secondary prevention. In spite of this consensus, however, certain controversy still exists about the cardiovascular risk of DM2. This controversy stems from the studies by Evans et al,6 who showed that the risk in patients with recently diagnosed DM2 is lower than that of persons who have already had a myocardial infarction. Since the publication of this report, frequent studies have appeared in support of one or other of the conclusions in an attempt to shed l Continue reading >>

Ecg (electrocardiogram): When You Need It And When You Don’t

Share on Facebook Share on Twitter Download (pdf) ECG (Electrocardiogram): When you need it and when you don’t An ECG (electrocardiogram) records the electrical activity of your heart at rest. It provides information about your heart rate and rhythm, and shows if there is enlargement of the heart due to high blood pressure (hypertension) or evidence of a previous heart attack (myocardial infarction). However, it does not show whether you have asymptomatic blockages in your heart arteries or predict your risk of a future heart attack. The resting ECG is different from a stress or exercise ECG or cardiac imaging test. You may need an ECG test if you have risk factors for heart disease such as high blood pressure, or symptoms such as palpitations or chest pain. Or you may need it if you already have heart disease. But in other cases, you may think twice about having this test. Here’s why: Usually, you do not need an ECG if you don’t have risk factors for heart disease or symptoms that suggest possible heart disease. The test is not useful in routine checkups for people who do not have risk factors for heart disease such as high blood pressure or symptoms of heart disease, like chest pain. Yet, many people with no risk factors or symptoms have an ECG as part of their routine checkups. There are better ways to prevent heart disease than routine ECGs. The ECG will not harm you. However, it can sometimes show mild nonspecific abnormalities that are not due to underlying heart disease, but cause worry and lead to follow-up tests and treatments that you do not need. When are ECGs needed? In some cases, it can be important to get this test. You should probably have an ECG if you have risk factors for an enlarged heart such as high blood pressure or symptoms of heart disease Continue reading >>

Electrocardiogram - Diabetes Self-management

Electrocardiogram - Diabetes Self-management

A test that measures the natural electrical activity of the heart. It is used to diagnose and evaluate heart problems. The electrical signals that regulate heartbeats start at the right atrium, one of the chambers located at the top of the heart, and travel to the bottom of the heart. As they travel through the heart, they signal the heart to contract in a synchronized fashion to pump blood throughout the blood vessels of the body. An electrocardiogram (also called an EKG or ECG) is used to determine how fast the heart is beating and whether the heart rhythm is steady or irregular. In so doing, it can uncover a number of potential heart problems, including a heart attack, lack of blood flow to the heart muscle, cardiac arrhythmias (irregular, fast, or slow heartbeats), and a heart that doesnt pump blood forcefully enough to meet the bodys needs. A commonly used type of electrocardiography, called a resting 12-lead EKG, is quick, simple, and painless. During this procedure, a technician attaches 12 electrodes to the skin on the chest, arms, and legs. Sometimes the technician shaves a persons body hair where the electrodes will be attached so that they will better adhere to the skin. As the person lies still for a few minutes, the electrodes pick up electrical signals from the heart and relay them to a machine that records these signals, either on graph paper or on a screen. The entire test takes only about 10 minutes, after which the electrodes are removed. This column is written by Robert Dinsmoor, a Contributing Editor of Diabetes Self-Management.

Prevalence And Determinants Of Electrocardiographic Abnormalities In African Americans With Type 2 Diabetes

Prevalence And Determinants Of Electrocardiographic Abnormalities In African Americans With Type 2 Diabetes

Volume 4, Issue 4 , December 2014, Pages 289-296 Prevalence and determinants of electrocardiographic abnormalities in African Americans with type 2 diabetes Open Access funded by Ministry of Health, Saudi Arabia Electrocardiographic (ECG) abnormalities are independently associated with poor outcomes in the general population. Their prevalence and determinants were assessed in the understudied African American population with type 2 diabetes. Standard 12-lead ECGs were digitally recorded in 635 unrelated African American-Diabetes Heart Study (AA-DHS) participants, automatically processed at a central lab, read, and coded using standard Minnesota ECG Classification. Age- and sex-specific prevalence rates of ECG abnormalities were calculated and logistic regression models were fitted to examine cross-sectional associations between participant characteristics and ECG abnormalities. Participants were 56% women with a mean age of 56years; 60% had at least one minor or major ECG abnormality [23% 1 major (or major plus minor), and 37% 1 minor (with no major)]. Men had a higher prevalence of 1 minor or major ECG abnormality (66.1% men vs. 55.6% women, p=0.0089). In univariate analysis, age, past history of cardiovascular disease, diabetes duration, systolic blood pressure, sex and statin use were associated with the presence of any (major or minor) ECG abnormalities. In a multivariate model including variables, female sex (OR [95% CI] 0.79 [0.67, 0.93]), statin use (0.79 [0.67, 0.93]) and diabetes duration (1.03 [1.0, 1.05]) remained statistically significant. Nearly three out of five African Americans with diabetes had at least one ECG abnormality. Female sex and statin use were significantly associated with lower odds of any ECG abnormality and diabetes duration was significa Continue reading >>

(1)Institute of Physiology, First Medical Faculty, Charles University, Prague, Czech Republic. [email protected] Diabetes mellitus (DM) has been known for many years to be associated with poorcardiovascular prognosis. Due to the sensitive neuropathy, the coronary arterydisease in diabetic patients is frequently asymptomatic. Also twelve leadsresting ECG can be within normal limits even in an advanced stage of coronaryartery disease. Therefore in addition to the standard ECG otherelectrocardiographic procedures started to be studied in order to find sometypical signs of myocardial damages caused by DM. Repeatedly reported resultsshowed in DM patients without cardiovascular complications the tachycardia,shortening of the QRS and QT intervals, increase of the dispersion of QTinterval, decreased amplitudes of depolarization waves, shortened activation timeof ventricular myocardium and a flattening of T waves confirmed by the lowervalue of maximum and minimum in repolarization body surface isopotential maps.Most of these changes are even more pronounced in patients with cardiac autonomicneuropathy. Comparison with similar ECG changes in other diseases suggests thatthe electrocardiographic changes in DM patients are not specific and that theyare particularly caused by an increased tone of the sympathetic nervous systemwhat was indirectly confirmed by the heart rate variability findings in thesepatients.

Heart Tests You May Need If You Have Diabetes

Carotidultrasound.It uses high-frequency sound waves to give your doctor a view of your major neck arteries,called the carotids. He'll be able to see if you have any narrowing of your arteries that's caused by a buildup of fatty deposits called plaque. Computerized tomography (CT) of theheartand calciumscores.This imaging test can spot calciumdeposits in vessels on your heart. More calcium means more coronary atherosclerosis -- a hardening and narrowing of your arteries. Your doctor uses the test results to figure out your odds of having heart trouble. Electrocardiogram (EKG).It's a test that measures the electrical activity of your heart. Your doctor will be able to check for things like: Ambulatory electrocardiogram (Holter monitor).This test measures the electrical activity of your heart while you go about your regular daily activities. Echocardiograph(echo).It uses ultrasound to give your doctor a graphic outline of your heart chambers and their movement. He'll be able to check your heart's structure and motion, and see how thick the heart muscle is and how well the heart pumps. Exercise stress test. It's a treadmill test that helps your doctor find out how much blood flow gets to your heart muscle when it works hard, like while you exercise. You'll learn if you have less blood flow in the arteries that send blood to your heart muscle. Your doctor can use this info to figure out what a safe level of exercise is for you. Coronary angiography.This procedure, also known as cardiac catheterization, can help your doctor check how many artery blockages you have and how severe they are.

Increased Cvd Risk With Ecg Abnormalities In Type 1 Diabetes

Increased CVD Risk With ECG Abnormalities in Type 1 Diabetes Increased CVD Risk With ECG Abnormalities in Type 1 Diabetes Minor ECG abnormalities did not significantly correlate with increased CVD risk. Electrocardiography (ECG) abnormalities may predict cardiovascular (CVD) risk in patients with type 1 diabetes, according to a study published in Diabetes Care.1 Patients with type 1 diabetes are at increased risk for CVD, the leading cause of death in this population.2,3- In the Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Interventions and Complications (EDIC) study, the majority of patients with type 1 diabetes developed new ECG abnormalities, and 1 in 6 participants acquired at least 1 new major ECG abnormality over a period of 16 years.4 Limited data suggest that ECG abnormalities may be associated with a greater risk for CVD in patients with type 1 diabetes.1 In the EDIC observational study, Elsayed Z. Soliman, MD, from Wake Forest School of Medicine in Winston-Salem, North Carolina, and colleagues evaluated the relationship between ECG abnormalities and CVD events in patients with type 1 diabetes.1 Based on the Minnesota Code ECG classification, ECG abnormalities were categorized as major (eg, complete left or right bundle branch block), minor (eg, isolated minor T wave or ST-segment abnormalities), or no abnormality. CVD events included stroke, congestive heart failure, first myocardial infarction, confirmed angina, coronary artery revascularization, or CVD-related death.1 Of 1306 patients, 155 (11.9%) experienced 1 or more CVD events during a median follow-up time of 19 years. Major ECG abnormalities predicted a more than 2-fold greater risk of CVD events compared with no abnormality (hazard ratio [HR] 2.10; 95% CI, 1.26-3.48) and no Continue reading >>

Ecg Test - Better Health Channel

Ecg Test - Better Health Channel

An electrocardiogram (ECG) is a medical test that detects heart problems by measuring the electrical activity generated by the heart as it contracts. ECGs from healthy hearts have a characteristic shape. If the ECG shows a different shape it could suggest a heart problem. A doctor may recommend an ECG for people who may be at risk of heart disease because there is a family history of heart disease, or because they smoke, are overweight, have diabetes, high cholesterol or high blood pressure. A doctor may also recommend an ECG for people who are displaying symptoms such as chest pain, breathlessness, dizziness, fainting or fast or irregular heartbeats. The ECG is a safe and non-invasive procedure with no known risks. An electrocardiogram (ECG) is a medical test that detects cardiac (heart) abnormalities by measuring the electrical activity generated by the heart as it contracts. The machine that records the patients ECG is called an electrocardiograph. The electrocardiograph records the electrical activity of the heart muscle and displays this data as a trace on a screen or on paper. This data is then interpreted by a medical practitioner. ECGs from normal, healthy hearts have a characteristic shape. Any irregularity in the heart rhythm or damage to the heart muscle can change the electrical activity of the heart so that the shape of the ECG is changed. A doctor may recommend an ECG for people who may be at risk of heart disease because there is a family history of heart disease, or because they smoke, are overweight, or have diabetes, high cholesterol or high blood pressure. They may also recommend an ECG if a person is experiencing symptoms such as: fast or irregular heartbeats (palpitations).
