Cardiac catheterization is a procedure that inserts a catheter into the heart to evaluate heart function and disease. It can diagnose conditions like coronary artery disease and determine if treatments like angioplasty are needed. The catheter is inserted into an artery and guided to the heart where contrast dye is injected to image the heart and arteries. An electrocardiogram (ECG) records the heart's electrical activity through electrodes on the skin to check for issues like heart attacks or abnormal rhythms. A computed tomography (CT) scan uses x-rays to create clear pictures of the heart and assess conditions like tumors without invasive procedures.
continuous or intermittent monitoring of heart activity, generally by electrocardiography, with assessment of the patient's condition relative to their cardiac rhythm.
Hemodynamic monitoring- Hemodynamic monitoring refers to the measurement of pressure, flow and oxygenation within the cardiovascular system. Hemodynamic monitoring is amandatory process in all the critical care units to assess the patients progress. This presentation is aimed to create an insight on Hemodynamic monitoring.

Your role and responsibility during an emergency in the cath lab. Communication is extremely important. This power point discusses how to do that. Effective teamwork and communication increases the success of resuscitation.
A moderately frequent illness called congestive heart failure occurs when the heart is unable to pump enough blood to meet the body's demands. It frequently happens as a result of a chronic illness or aging. The body makes an effort to make up for this by boosting blood salt levels and fluid retention.
Swelling, weight gain, and shortness of breath may result from this. Diabetes and high blood pressure are other conditions linked to congestive heart failure. Congestive heart failure, however, is most frequently brought on by coronary artery disease (CAD). This occurs when the arteries that carry blood to the heart start to constrict and narrow.
When calling a doctor is important to question Dr. Sumit shejol Cardiologist from Hrudaysparsh Clinic Suggests that if you recognize the majority of the symptoms of heart failure. Certain signs and symptoms, such as chest pain, acute breathlessness, an irregular heartbeat, extreme weakness, or fainting, demand rapid medical attention. Do not delay in seeking assistance, do not self-diagnose, and do not self-medicate if you feel any of that. Some of these symptoms may also be a sign of heart failure or another serious lung, heart, or cardiovascular disease. Your condition is stabilized as emergency room doctors try to identify the source of your symptoms. Call your doctor right away if you've already been given a heart failure diagnosis and you realize that your symptoms have gotten worse or a new symptom has appeared.
Congestive heart failure is a fatal condition with a high mortality rate. Congestive heart failure has a wide range of risk factors. Smoking, high blood pressure, diabetes, high cholesterol, being obese, and having experienced a heart attack in the past are some of them. It can also be brought on by a hereditary condition like cardiomyopathy. The condition can cause the heart muscle to expand and become excessively thick, which can result in heart failure. Congestive heart failure can be exacerbated by lifestyle choices including smoking, excessive alcohol intake, or tobacco use.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

2. Cardiac Catheterization Cardiac catheterization (also called cardiac cath or coronary angiogram) is a procedure that allows your doctor to "see" how well your heart is functioning. The test involves inserting a long, narrow tube, called a catheter, into a blood vessel in your arm or leg, and guiding it to your heart with the aid of a special X-ray machine. Contrast dye is injected through the catheter so that X-ray movies of your valves, coronary arteries and heart chambers can be created.
3. Purpose of Cardiac Catheter Evaluate or confirm the presence of heart disease (such as coronary artery disease, heart valve disease or disease of the aorta). Evaluate heart muscle function. Determine the need for further treatment (for example, angioplasty or bypass surgery ) At many medical centers, cardiac catheterization is used to perform several interventional, or therapeutic, procedures to open blocked
4. Procedure For Cardiac Catheterization Local anaesthetic is injected into the skin to numb the area. A small puncture is then made with a needle in either the femoral artery in the groin or the radial artery in the wrist, before a guidewire is inserted into the arterial puncture. A plastic sheath (with a stiffer plastic introducer inside it) is then threaded over the wire and pushed into the artery (Seldinger technique). The wire is then removed and the side-port of the sheath is aspirated to ensure arterial blood flows back. It is then flushed with saline. Catheters are inserted using a long guidwire and moved towards the heart. Once in position above the aortic valve the guidewire is then removed. The catheter is then engaged with the origin of the coronary artery (either left main stem or right coronary artery) and x-ray opaque iodine-based dye is injected to make the coronary vessels show up on the x-ray fluoroscopy image.
5. Procedure For Cardiac Catheterization When the necessary procedures are complete, the catheter is removed. Firm pressure is applied to the site to prevent bleeding. This may be done by hand or with a mechanical device. Other closure techniques include an internal suture and plug. If the femoral artery was used, the patient will probably be asked to lie flat for several hours to prevent bleeding or the development of a hematoma. Cardiac interventions such as the insertion of a stent prolong both the procedure itself as well as the post-catheterization time spent in allowing the wound to clot. A cardiac catheterization is a general term for a group of procedures that are performed using this method, such as coronary angiography, as well as left ventrical angiography. Once the catheter is in place, it can be used to perform a number of procedures including angioplasty, angiography, balloon septostomy, and an Electrophysiology study.
6. Electrical Activity MonitoringElectocardiogram (ECG) An electrocardiogram (ECG or EKG) is one of the simplest and fastest procedures used to evaluate the heart. Electrodes (small, plastic patches) are placed at certain locations on the chest, arms, and legs. When the electrodes are connected to an ECG machine by lead wires, the electrical activity of the heart is measured, interpreted, and printed out for the physician's information and further interpretation.
7. Purpose of ECG Check the heart's electrical activity. Find the cause of unexplained chest pain, which could be caused by a heart attack, inflammation of the sac surrounding the heart (pericarditis), or angina. Find the cause of symptoms of heart disease, such as shortness of breath, dizziness, fainting, or rapid, irregular heartbeats (palpitations). Find out if the walls of the heart chambers are too thick (hypertrophied). Check how well medicines are working and whether they are causing side effects that affect the heart. Check how well mechanical devices that are implanted in the heart, such as pacemakers, are working to control a normal heartbeat. Check the health of the heart when other diseases or conditions are present, such as high blood pressure, high cholesterol, cigarette smoking, diabetes, or a family history of early heart disease.
8. Understanding ElectrocardiogramThe heart's electrical conduction system The heart is, in the simplest terms, a pump made up of muscle tissue. Like all pumps, the heart requires a source of energy in order to function. The heart's pumping energy comes from an inborn electrical conduction system. An electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node), which is a small mass of specialized tissue located in the right atrium (right upper chamber) of the heart.
9. Understanding ElectrocardiogramThe heart's electrical conduction system The sinus node generates an electrical stimulus regularly at 60 to 100 times per minute under normal conditions. This electrical stimulus travels down through the conduction pathways (similar to the way electricity flows through power lines from the power plant to your house) and causes the heart's chambers to contract and pump out blood. The right and left atria (the two upper chambers of the heart) are stimulated first and contract a short period of time before the right and left ventricles (the two lower chambers of the heart). The electrical impulse travels from the sinus node to the atrioventricular (AV) node, where it stops for a very short period, then continues down the conduction pathways via the AV bundle of His" into the ventricles. The "bundle of His" divides into right and left pathways to provide electrical stimulation to both ventricles. This electrical activity of the heart is measured by an electrocardiogram. By placing electrodes at specific locations on the body (chest, arms, and legs), a graphic representation, or tracing, of the electrical activity can be obtained. Changes in an ECG from the normal tracing may indicate one or more of several heart-related conditions.
10. Understanding ElectrocardiogramUnderstanding ECG tracings The first short upward notch of the ECG tracing is called the "P wave." The P wave indicates that the atria (the two upper chambers of the heart) are contracting to pump out blood. The next part of the tracing is a short downward section connected to a tall upward section. This next part is called the "QRS complex." This part indicates that the ventricles (the two lower chambers of the heart) are contracting to pump out blood.
11. Understanding ElectrocardiogramUnderstanding ECG tracings The next short upward segment is called the "ST segment." The ST segment indicates the amount of time from the end of the contraction of the ventricles to the beginning of the rest period before the ventricles begin to contract for the next beat. The next upward curve is called the "T wave." The T wave indicates the resting period of the ventricles. When the physician views an ECG, he/she studies the size and length of each part of the ECG. Variations in size and length of the different parts of the tracing may be significant. The tracing for each lead of a 12-lead ECG will look different, but will have the same basic components as described above. Each lead of the 12-lead ECG is "looking" at a specific part of the heart, so variations in a lead may indicate a problem with the part of the heart associated with a particular lead.
12. Imaging ProceduresComputed Tomography (CT or CAT) Scan Cardiac computed tomography (to-MOG-rah-fee), or cardiac CT, is a painless test that uses an x-ray machine to take clear, detailed pictures of your heart. It's a common test for showing problems of the heart. During a cardiac CT scan, the x-ray machine will move around your body in a circle and take a picture of each part of your heart. Because an x-ray machine is used, cardiac CT scans involve radiation. However, the amount of radiation used is small. This test gives out a radiation dose similar to the amount of radiation you’re naturally exposed to over 3 years. There is a very small chance that cardiac CT will cause cancer.
13. Purpose of Computed Tomography to assess the chest and its organs for tumors and other lesions, injuries, intra-thoracic bleeding, infections, unexplained chest pain, obstructions, or other conditions, particularly when another type of examination, such as x-rays or physical examination, is not conclusive to evaluate the effects of treatment of thoracic tumors. Another use of chest CT is to provide guidance for biopsies and/or aspiration of tissue from the chest
14. Procedures for Computed Tomography In computed tomography, the x-ray beam moves in a circle around the body. This allows many different views of the same organ or structure. The x-ray information is sent to a computer that interprets the x-ray data and displays it in a two-dimensional (2D) form on a monitor. While many images are taken during a CT scan, in some cases the patient receives the same or less radiation exposure than with a single standard x-ray. CT scans may be done with or without "contrast." Contrast refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations may require you to fast for a certain period of time before the procedure. Your physician will notify you of this prior to the procedure.
15. Procedures for Computed Tomography CT scans of the chest can provide more detailed information about organs and structures inside the chest than standard x-rays of the chest, thus providing more information related to injuries and/or diseases of the chest (thoracic) organs. CT scans of the chest may also be used to visualize placement of needles during biopsies of thoracic organs or tumors, or during aspiration (withdrawal) of fluid from the chest. CT scans of the chest are useful in monitoring tumors and other conditions of the chest before and after treatment.
