This document proposes a new hypothesis that some heart diseases may be caused by endogenous toxicological factors within the body over time. It suggests that metabolic and catabolic imbalances can create conditions like congestive heart failure, and that allowing sufficient time to restore balance through rest can resolve pathologies. Coronary artery spasm is discussed as an example that may be triggered by activated platelets releasing vasoconstrictor substances. The hypothesis is that better understanding endogenous local toxicity and its kinetics over time could provide new insights into the etiology, diagnosis and treatment of certain heart conditions.

Despite recent advances, the diagnosis and management of heart failure evades the clinicians. The etiology of congestive heart failure (CHF) in the Indian scenario comprises of coronary artery disease, diabetes mellitus and hypertension. With better insights into the pathophysiology of CHF, biomarkers have evolved rapidly and received diagnostic and prognostic value. In CHF biomarkers prove as measures of the extent of pathophysiological derangement; examples include biomarkers of myocyte necrosis, myocardial remodeling,
neurohormonal activation, etc.
Management of Takotsubo Syndrome: A Comprehensive ReviewNicolas Ugarte
Takotsubo syndrome (TTS), also known as Takotsubo cardiomyopathy, is a transient left
ventricular wall dysfunction that is often triggered by physical or emotional stressors. Although
TTS is a rare disease with a prevalence of only 0.5% to 0.9% in the general population, it is
often misdiagnosed as acute coronary syndrome. A diagnosis of TTS can be made using Mayo
diagnostic criteria. The initial management of TTS includes dual antiplatelet therapy,
anticoagulants, beta-blockers, angiotensin-converting enzyme inhibitors or aldosterone
receptor blockers, and statins. Treatment is usually provided for up to three months and has a
good safety profile. For TTS with complications such as cardiogenic shock, management
depends on left ventricular outflow tract obstruction (LVOTO). In patients without LVOTO,
inotropic agents can be used to maintain pressure, while inotropic agents are contraindicated
in patients with LVOTO. In TTS with thromboembolism, heparin should be started, and
patients should be bridged to warfarin for up to three months to prevent systemic emboli. Our
comprehensive review discussed the management in detail, derived from the most recent
literature from observational studies, systematic review, and meta-analyses.
Causes for syncope are multifaceted. Hormonal etiology, specifically hypothyroidism, is associated with cardiac arrhythmias [1]. Sinus bradycardia, low voltage, nonspecific T-wave changes and dissociative atrioventricular (AV) abnormalities are some of descriptive electrocardiographic features [2]. In the majority of well know clinical presentations complete AV block requires the insertion of a permanent pacemaker. However hypothyroidism related bradycardia and consequential symptomatic AV blocks could be reversible with timely and proper management.
We report a case of severe hypothyroidism resulting in insertion of transient pacemaker with favorable clinical course and fully reversible complete AV block after accordant pharmacological hormonal substitution.

Cardiovascular disease is the most prevalent class of diseases in the world. Every year more individuals die from cardiovascular diseases than any other illness. Diagnosis and treatment options are limited despite current and past efforts. The molecular mechanisms that lead to the onset and progression of detrimental phenotypes in the heart remain largely elusive. To battle against the ever-increasing number of cardiovascular disease-related deaths, major goals of cardiovascular proteomics studies include the development and
utilization of cutting-edge proteomics technologies to map the dynamic cardiac and vascular proteomes, elucidate cardiovascular disease mechanisms, identify candidate therapeutic targets and provide a clinically useful diagnosis as well as risk prediction. Current emphasis is given to promoting the development and adoption of quantitative protein assays targeting highly relevant cardiovascular proteins, such that translation of proteomics technologies may be expedited. Current proteomic approaches in cardiovascular proteomics are discussed.

In philosophical and spiritual literature this is called a stepwise process of self realization or KRAMA (stepwise) YOGA. NAMASMARAN (JAP, JAAP, JIKRA, SUMIRAN, and SIMARAN i.e. remembering and reorienting to the true self) is acclaimed to be universally and unconditionally helpful in this process. Apart from the study of physiology, pathophysiology, statistical surveys, clinical studies, experimental work; the verification of this hypothesis is essentially through the practice of NAMASMARAN.
Coarctation of aorta is characterized by narrowing of the aortic lumen. Complex lesion are complicated by associated cardiac anomalies and picked in infancy while simple coarctations are not diagnosed until adulthood when it manifests as secondary hypertension or its complications. We are reporting a case of severe coarctation of aorta which presented as ST elevation on anterior chest leads with severe sudden onset left sided neck pain mimicking anterior wall myocardial infarction and patient was thrombolysed due to dynamic ECG changes and new onset severe left sided neck pain.
The autonomic nervous system (ANS) controls all body functions. Dysregulation of this system may be responsible of bradycardia. The main objective of our study is to describe the autonomic profile of patients with bradycardia and to determine, through testing cardiovascular autonomic reflexes its involvement in the pathogenesis of idiopathic symptomatic bradycardia.
The study objective was to evaluate the cardioprotective activity of Biofield Energized test item (DMEM) in rat cardiomyocytes (H9c2) cells. The test item (DMEM medium) was divided into three parts, first part received one-time Consciousness Energy Healing Treatment by a renowned Biofield Energy Healer, Dahryn Trivedi and was labeled as the one-time Biofield Energy Treated (BT-I) DMEM, while second part received the two-times Biofield Energy Treatment and is denoted as BT-II DMEM.
Essential hypertension, the most common type, is an important cause of morbidity and mortality in the elderly, a rapidly growing section of the population. It is a sad reality that until the 1950s treating benign hypertension was not thought to be necessary. The tragic death of Franklin Delano Roosevelt on April 12, 1945 at the age of 63 years, with a blood pressure of 350/195mmHg, and without treatment shocked the healthcare community.
Beats classification is an essential step in the ECG signal analysis for cardiac arrhythmias detection. There are multiple alternatives to solve this problem, but these are considerably reduced when re-al-time restrictions are added to the analysis. The goal of this work is to expose an optimal solution based mainly on the use of voltage values of the signal in the time domain and compare it with other based on Daubechies’ Wavelets analysis. Several measures are used in both feature spaces to determine the similarity of every beat to a patient’s specific patterns and, after that, a method similar to clustering’s algorithms is used to assign a class to each.
Coronary artery diseases (CAD) known as atherosclerotic heart disease, atherosclerotic cardiovascular disease, coronary heart disease (CHD), or ischemic heart disease (IHD). CAD is the largest contributor of cardiovascular diseases (CVDs) and mortality rate is due in prevalence to atherosclerosis, a chronic inflammatory condition of the arterial wall. Unfortunately, myocardial infarction (MI) is still a first common manifestation of CHD and, in about 50% of patients; angina pectoris is the first symptom of the pathology.
Intraoperative aortic dissection during cardiac surgery is infrequent, complicating surgical intervention in 0.04 - 1% of cases. Dissections can occur anywhere, most often as a result of direct mechanical damage at the location of the side clamp, site of cannulation of the aorta, or at the site of proximal anastomosis and may manifest as hematoma, bleeding at the cannulation site or bleeding from the proximal anastomoses or aortic suture lines. Delayed diagnosis and treatment can lead to extremely (23-41%) high mortality rate.
Hemorheological indexes, living habits, medical history and genetics factor are primary risk factors in Coronary Heart Disease (CHD). In the present study the relation of all factors to the severity of CHD was examined. The data of 282 patients (mean age: 60±9 years) diagnosed with CHD and 229 healthy controls (mean age: 59±7 years) from Wenzhou Medical University were analyzed.
In 2001, a mathematical model for determining the surface area of the left ventricle (LV) and another one for its volume (VLV) was presented. Both were based on the consideration that the geometry of a normal LV is similar to the one of a Truncated Prolate Spheroid (TPS).
Transcatheter Aortic Valve Replacement (TAVR) had become a novel and secure procedure to treat aortic stenosis that had become more accepted over the years; the approach and different types of device improve the life expectancy, diminish the complications and costs in public health. Along with the improvement in technology the minimalist approach had gain popularity to ameliorate the overall patient health.
Despite the advances in diagnostic methods and techniques for surgical treatment in the last two decades, aortic diseases remain a major cause of mortality and cardiovascular morbidity, challenging physicians and molecular biologists. It is believed that about 600 million years ago, during the Cambrian period, variant forms of life appeared, among them were the oxygen-producing cyano bacteria.
The central venous access is one of the most common procedures in interventional nephrology [1-3]. One of the known complications of this procedure is the right branch lesion of the His bundle that leads to temporary or permanent blockage.
Infective endocarditis is a life-threatening disease caused by bacterial infection of the endothelium and cardiac valves, either native or prosthetic. In the present work the role of the new microbiological techniques (techniques of detection and amplification of the subunit 16 ribosomal sRNA by means of the chain reaction of the polymerase in blood or tissue, fluorescent in situ hybridization, and matrix-assisted laser is reviewed desorption/ ionization time-of-flight mass spectrometry (MALDI-TOF MS) in the diagnosis of infective endocarditis.
Epidemiological and clinical evidence confirm that hearts are sensitive to ionizing radiation (IR). They are even more radiosensitive than formerly believed. Mechanistic studies show that the radiosensitivity is not due to the heart muscles but mainly to the cardiovascular system (CV).
Coronary artery bypass graft surgery is the most frequently performed surgical intervention for relieving consequences associated with myocardial infarction. Despite its efficiency and advances in the methodology of collection, preservation and early onset antithrombotic treatment, vein graft failure is estimated between 15 and 30% during the first year. After 10 years of surgery, only 50% of these grafts are free of significant stenosis. Thrombosis, intimalhyperplasia, and accelerated atherosclerosis are the primary events pathophysiological of vein graft.
In cardiology practice, we often come across patients presenting with anginal pain who undergo coronary angiogram which reveals either normal or non-obstructive epicardial coronaries. Importance is given to epicardial coronaries and the coronary microvasculature which could be the cause of angina is often overlooked. These patients are then labeled to have non-cardiac chest pain and musculoskeletal or psychogenic etiology is suggested. However, with growing interest in coronary microvasculature which are the tiny blood vessels at the tissue level in myocardium, diagnostic modalities and treatment options for coronary microvascular disease are being explored.
Coronary angioplasty has revolutionized the management of coronary artery disease. It has not ceased to develop to become the reference method of myocardial revascularization. The aim of our study is to evaluate the ultrasound parameters of left ventricular function after coronary angioplasty. This is a prospective analytical study including patients with stable coronary artery disease with a known coronary artery anatomy programmed for coronary angioplasty. Transthoracic echocardiography was performed four hours before and seven days after myocardial revascularization.
Cardiomyopathies are heart muscle diseases originated from a series of aggressions, such as genetic defects, cardiac myocyte injury or infiltration of myocardial tissue. Dilated cardiomyopathy (DCM) is characterized by an impairment of the left ventricular or biventricular contraction, caused by familial, genetic, viral, autoimmune, alcoholic, toxic, or of unknown cause.
A hypothesis is presented which suggests that the cardiac L-type calcium channel opens in a stochastic fashion as the calcium channel protein complex moves around in the lipid of the outer leaflet of the sarcolemma. Opening occurs when there is release of calcium ions that are bound in the polarised state to anionic phospholipid of the inner leaflet, the release being a consequence of proton penetration into the sarcolemma upon depolarisation.
Catheter ablation of premature ventricular complexes (PVCs) is an effective treatment when disabling symptoms or ectopy-induced cardiomyopathy are present in patients refractory to pharmacological therapy. When PVCs originate close to His bundle, radiofrequency ablation is burdened by unacceptable risk of conduction pathways damage or atrio-ventricular block. Here we report a case of a patient with highly symptomatic ventricular ectopy originating close to His bundle undergoing successfull cathetercryoablation.
