J Wave and Cardiac Death in Inferior Wall Myocardial Infarction
ORIGINAL ARTICLES Arrhythmia 2015;16(2):67-77 J Wave and Cardiac Death in Inferior Wall Myocardial Infarction Myung-Jin Cha, MD; Seil Oh, MD, ABSTRACT PhD, FHRS Background and Objectives: The clinical significance of J wave Department of Internal Medicine, Seoul National University presentation in acute myocardial infarction (AMI) patients remains Hospital, Seoul, Korea unclear. We hypothesized that J wave appearance in the inferior leads and/or reversed-J (rJ) wave in leads V1-V3 is associated with poor prognosis in inferior-wall AMI patients. Subject and Methods: We enrolled 302 consecutive patients with inferior-wall AMI who were treated with percutaneous coronary in- tervention (PCI). Patients were categorized into 2 groups based on electrocardiograms before and after PCI: the J group (J waves in in- ferior leads and/or rJ waves in leads V1-V3) and the non-J group (no J wave in any of the 12 leads). We compared patients with high am- plitude (>2 mV) J or rJ waves (big-J group) with the non-J group. The cardiac and all-cause mortality at 6 months and post-PCI ventricular arrhythmic events ≤48 hours after PCI were analyzed. Results: A total of 29 patients (including 19 cardiac death) had died. Although all-cause mortality was significantly higher in the post-PCI J group than in the non-J group (p=0.001, HR=5.38), there was no difference between the groups in cardiac mortality. When compar- ing the post-PCI big-J group with the non-J group, a significant dif- ference was found in all-cause mortality (n=29, p=0.032, HR=5.4) and cardiac mortality (n=19, p=0.011, HR=32.7). -
General Signs and Symptoms of Abdominal Diseases
General signs and symptoms of abdominal diseases Dr. Förhécz Zsolt Semmelweis University 3rd Department of Internal Medicine Faculty of Medicine, 3rd Year 2018/2019 1st Semester • For descriptive purposes, the abdomen is divided by imaginary lines crossing at the umbilicus, forming the right upper, right lower, left upper, and left lower quadrants. • Another system divides the abdomen into nine sections. Terms for three of them are commonly used: epigastric, umbilical, and hypogastric, or suprapubic Common or Concerning Symptoms • Indigestion or anorexia • Nausea, vomiting, or hematemesis • Abdominal pain • Dysphagia and/or odynophagia • Change in bowel function • Constipation or diarrhea • Jaundice “How is your appetite?” • Anorexia, nausea, vomiting in many gastrointestinal disorders; and – also in pregnancy, – diabetic ketoacidosis, – adrenal insufficiency, – hypercalcemia, – uremia, – liver disease, – emotional states, – adverse drug reactions – Induced but without nausea in anorexia/ bulimia. • Anorexia is a loss or lack of appetite. • Some patients may not actually vomit but raise esophageal or gastric contents in the absence of nausea or retching, called regurgitation. – in esophageal narrowing from stricture or cancer; also with incompetent gastroesophageal sphincter • Ask about any vomitus or regurgitated material and inspect it yourself if possible!!!! – What color is it? – What does the vomitus smell like? – How much has there been? – Ask specifically if it contains any blood and try to determine how much? • Fecal odor – in small bowel obstruction – or gastrocolic fistula • Gastric juice is clear or mucoid. Small amounts of yellowish or greenish bile are common and have no special significance. • Brownish or blackish vomitus with a “coffee- grounds” appearance suggests blood altered by gastric acid. -
Heart Failure
Heart Failure Sandra Keavey, DHSc, PAC, DFAAPA Defined Heart failure (HF) is a common clinical syndrome resulting from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood. HF may be caused by disease of the myocardium, pericardium, endocardium, heart valves, vessels, or by metabolic disorders Epidemiology-Magnitude Heart failure disproportionately affects the older population. Approximately 80% of all cases of heart failure in the United States occur in persons aged 65 years and older. In the older population, heart failure accounts for more hospital admissions than any other single condition. Following hospitalization for heart failure, nearly half are readmitted within 6 months. Epidemiology-Prevalence Prevalence. About 5.1 million people in the United States have heart failure. One in 9 deaths in 2009 included heart failure as contributing cause. About half of people who develop heart failure die within 5 years of diagnosis. 25% of all heart failure patients are re-admitted to the hospital within 30 days. 50% of all heart failure patients are re-admitted to the hospital within 6 months. Systolic vs Diastolic There are two common types of heart failure Systolic HF Systolic HF is the most common type of HF Now referred to as HFrEF Heart Failure reduced Ejection Fraction The heart is weak and enlarged. The muscle of the left ventricle loses some of its ability to contract or shorten. Diastolic HF Diastolic HF is not an isolated disorder of diastole; there are widespread abnormalities of both systolic and diastolic function that become more apparent with exercise. -
Unstable Angina with Tachycardia: Clinical and Therapeutic Implications
Unstable angina with tachycardia: Clinical and therapeutic implications We prospectively evaluated 19 patients with prolonged chest pain not evolving to myocardiai infarction and accompanied with reversible ST-T changes and tachycardia (heart rate >lOO beats/min) in order to correlate heart rate reduction with ischemic electrocardiographic (ECG) changes. Fourteen patients (74%) received previous long-term combined treatment with nifedipine and nitrates. Continuous ECG monitoring was carried out until heart rate reduction and at least one of the following occurred: (1) relief of pain or (2) resolution of ischemic ECG changes. The study protocol consisted of carotid massage in three patients (IS%), intravenous propranolol in seven patients (37%), slow intravenous amiodarone infusion in two patients (lo%), and intravenous verapamil in four patients (21%) with atrial fibrillation. In three patients (16%) we observed a spontaneous heart rate reduction on admission. Patients responded with heart rate reduction from a mean of 126 + 10.4 beats/min to 64 k 7.5 beats/min (p < 0.005) and an ST segment shift of 4.3 k 2.13 mm to 0.89 k 0.74 mm (p < 0.005) within a mean interval of 13.2 + 12.7 minutes. Fifteen (79%) had complete response and the other four (21%) had partial relief of pain. A significant direct correlation was observed for heart rate reduction and ST segment deviation (depression or elevation) (f = 0.7527 and 0.8739, respectively). These patients represent a unique subgroup of unstable angina, in which the mechanism responsible for ischemia is excessive increase in heart rate. Conventional vasodilator therapy may be deleterious, and heart rate reduction Is mandatory. -

The J Wave of the ECG. Concepts Compiled by Dr
The J wave of the ECG. Concepts Compiled by Dr. Andrés R. Pérez Riera The J wave is a positive deflection in the ECG normal (present in 2%–14% of healthy individuals and is more prevalent in young males, particularly if athletic and African descent. Additionally, ERP is a common finding in young teen athletes (the prevalence in the athletic population rises to 20-90%.).1 In this population ERP in both inferior and lateral leads is more common (18.2%) than isolated inferior (9.1%) or lateral (8.2%) ERP. Young age might be a contributing factor in causing a more diffuse repolarization abnormality. 2 or pathological that occurs approximately (There is an overlap of ≈10 msec. 3) after the junction between the end of the QRS complex and the beginning of the ST segment, also known as the J point (junction point), QRS end, J-junction, ST0 [zero millisecond] or ST beginning to occur after the notch/slur or J wave 4. It is described as J deflection as slurring/lambda 5 or notching of the terminal portion of QRS complex. Currently, J waves, is defined as an elevation of the QRS-ST junction ≥1 mm either as QRS slurring or notching in at least 2 contiguous leads. Additionally, when it becomes more accentuated, it may appear as a small, R wave (R′) or ST segment elevation. The term J deflection or J-wave has been used to designate the formation of the wave produced when there is a large, prominent deviation of the J point from the baseline with two shapes: notching/spike-and- slurring/lambda 5 or dome 6 variety. -
Heart Valve Disease: Mitral and Tricuspid Valves
Heart Valve Disease: Mitral and Tricuspid Valves Heart anatomy The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen- rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves that regulate blood flow. The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. The mitral valve is located on the left side of the heart, between the left atrium and the left ventricle. This valve has two leaflets that allow blood to flow from the lungs to the heart. The tricuspid valve is located on the right side of the heart, between the right atrium and the right ventricle. This valve has three leaflets and its function is to Cardiac Surgery-MATRIx Program -1- prevent blood from leaking back into the right atrium. What is heart valve disease? In heart valve disease, one or more of the valves in your heart does not open or close properly. Heart valve problems may include: • Regurgitation (also called insufficiency)- In this condition, the valve leaflets don't close properly, causing blood to leak backward in your heart. • Stenosis- In valve stenosis, your valve leaflets become thick or stiff, and do not open wide enough. This reduces blood flow through the valve. Blausen.com staff-Own work, CC BY 3.0 Mitral valve disease The most common problems affecting the mitral valve are the inability for the valve to completely open (stenosis) or close (regurgitation). -

Association of Cardiomegaly with Coronary Artery Histopathology and Its Relationship to Atheroma
32 Journal of Atherosclerosis and Thrombosis Vol.18, No.1 Coronary Histopathology in Cardiomegaly 33 Original Article Association of Cardiomegaly with Coronary Artery Histopathology and its Relationship to Atheroma Richard Everett Tracy Department of Pathology, Louisiana State University Health Sciences Center, New Orleans, USA Aims: Hypertrophied hearts at autopsy often display excessive coronary artery atherosclerosis, but the histopathology of coronary arteries in hearts with and without cardiomegaly has rarely been com- pared. Methods: In this study, forensic autopsies provided hearts with unexplained enlargement plus com- parison specimens. Right coronary artery was opened longitudinally and flattened for formalin fixa- tion and H&E-stained paraffin sections were cut perpendicular to the endothelial surface. The mi- croscopically observed presence or absence of a necrotic atheroma in the specimen was recorded. At multiple sites far removed from any form of atherosclerosis, measurements were taken of intimal thickness, numbers of smooth muscle cells (SMC) and their ratio, the thickness per SMC, averaged over the entire nonatheromatous arterial length. When the mean thickness per SMC exceeded a cer- tain cutoff point, the artery was declared likely to contain a necrotic atheroma. Results: The prevalence of specimens with necrotic atheromas increased stepwise with increasing heart weight, equally with fatal or with incidental cardiomegaly, and equally with hypertension- or obesity-related hypertrophy, rejecting further inclusion of appreciable age, race, or gender effects. The prevalence of specimens with thickness per SMC exceeding the cutoff point was almost always nearly identical to the prevalence of observed necrotic atheroma, showing the two variables to be tightly linked to each other with quantitative consistency across group comparisons of every form. -
