Obesity

According to ObesityInAmerica.org, obesity is the second leading cause of preventable death in the U.S. Approximately 127 million adults in the U.S. are overweight, 60 million obese, and 9 million severely obese. Furthermore, an estimated 65.2 percent of U.S. adults, age 20 years and older, and 15 percent of children and adolescents are overweight and 30.5 percent are currently obese.

Obesity defined

Obesity is a complex disease in which having too much body fat increases a person’s risk for developing other health problems. Obesity is measured by body mass index (BMI), a calculation that shows weight in relation to height. Click here to calculate your BMI.

As BMI increases, the risk of some diseases increases. A BMI of 30 or above is considered obese in adults, which means a person is at a higher risk for certain diseases, including heart disease, high blood pressure, and coronary artery disease (CAD). However, BMI is only one of many factors used to predict the risk of developing a disease.

Health risks of obesity

Overweight and obese people are prone to cardiovascular diseases (CVD), including heart attack, congestive heart failure, sudden cardiac death, angina and abnormal heart rhythm.

More than 80 percent of people with the most common form of diabetes, Type 2, are obese or overweight. Obesity complicates the management of Type 2 diabetes by increasing insulin resistance and glucose intolerance, which makes drug treatment for the disease less effective.

Obesity has a negative effect on lipid levels in the blood, which often leads to the development of a condition known as dyslipidemia, which is a primary risk factor for coronary artery disease (CAD).

The majority of patients diagnosed with Polycystic Ovary Syndrome (PCOS), the most common hormonal disorder in reproductive-age women, are either overweight or obese. PCOS is a leading cause of infertility. In addition, PCOS causes significant insulin resistance, thereby increasing the woman’s risk of developing diabetes.

Treatments for obesity

Research has shown that surgery may work better than diet to treat obesity.

Surgery may be an option if you have a body mass index (BMI) of 40 or more. It may also be an option if you have a BMI of 35 and another health problem related to your weight, such as diabetes or arthritis.

The surgery helps by causing significant weight loss thereby reducing obesity-related health problems, including diabetes, type 2 and high blood pressure.

Two types of surgery are used to treat obesity. A restrictive operation such as stomach stapling or adjustable gastric banding decreases food intake, usually by decreasing the size of the stomach. A malabsorptive operation such as a Roux-en-Y gastric bypass or a biliopancreatic diversion restricts food intake and decreases the digestion and absorption of food.

Treatment cost

In the US, the surgery may cost tens of thousands of dollars. If you are uninsured or underinsured, this may mean a huge out-of-pocket expense for your treatment. However, if you opt to have the same surgery overseas you may be out on your healthy way for just a fraction of the cost in the US.

CT – Scan

Provided by Escorts Heart Institute
Brought to you by Healthbase

CT (Computed Tomography) is a diagnostic test that combines the use of x-rays with computer technology. A series of x-rays beams from different angles around the body are used to show cross sectional images of the patient’s body. The images so obtained are assembled in a computer into a three- dimensional picture that can display organs, bones & tissues in great detail.

In spiral CT the examination table advances at a constant rate through the scanner gantry. While the x-ray tube rotates continuously around the patient, tracing a spiral path through the patient. This spiral path gathers continuous data with no gaps between images.

CT Angiography (CTA) is an examination that is used to visualize blood vessels in many areas of the body including the brain, kidneys, pelvis and the arteries serving the lungs. Compared to catheter angiography, which involves injecting contrast medium into an artery CTA is much less invasive & a more patient friendly procedure; contrast medium is injected into a vein rather than an artery.

Why is it done?
CT imaging offers detailed views of different types of tissue, including the lung, bones, soft tissues and blood vessels Using specialized equipment & expert technician to create CT scans of the body , radiologists can more easily diagnose problems such as cancers, cardiovascular diseases ,infectious diseases, trauma & musculoskeletal disorders.

How is it done?
Patient is asked to change into a gown before the examination & to remove jewellery, eyeglasses and metal objects depending on the part of the body that is being scanned.

The CT technician begins by positioning the patient on the CT table. The patient’s body is supported by the safety straps & is asked to lie very still and follow the instructions of the technician while the scanning is being performed. During the scanning, the technician can see, hear & speak to the patient at all times.

A CT examination often requires the use of different contrast agents to enhance the visibility of certain tissues or blood vessels. The contrast agent may be injected directly into the blood stream, swallowed or administered by enema, depending on the type of examination. Before administering the contrast agent the radiologist or technician will ask whether the patient has any allergies, especially to medications, iodine and whether the patient has a history of diabetes, asthma, a heart condition, kidney problem or thyroid conditions as these conditions indicate a higher risk of reaction to the contrast agent. Fortunately with the safety of the newest contrast agents the adverse effects are very rare.

The department of Radiodiagnosis & Imaging at EHIRC is well equipped to deal any emergency. A CT examination usually takes from 15 minutes to half an hour. When the exam is over, the patient may be asked to wait until the images are examined to determine if more images are needed.

For the CT Angiography contrast medium is injected into a vein with an automatic injector machine that controls the timing & rate of injection, which may continue during part of the time images are recorded. Afterwards the images are reviewed & some will be repeated, if necessary. The real work of CT angiography comes after the images are acquired, when powerful computer programs process the images & make it possible to display them in different ways.

When it is done/advised ?
It is done when clinicians prescribe it after examining patient and going through his/her records. The radiologists also advise for CT scan when routine x-rays and ultrasonography fail to provide adequate information. It is better device for interventional procedures.

Coronary artery bypass graft surgery (CABG)

Provided by Escorts Heart Institute
Brought to you by Healthbase

Coronary artery bypass graft surgery (CABG) involves sewing one end an artery or vein above a blocked coronary artery and the other end below the blockage, thereby allowing blood an alternative means to get to the heart. The arteries or veins used for the bypass (which are known as “grafts”) are usually obtained from the leg or the chest wall. Bypass surgery may not be possible if the coronary artery is heavily calcified or if the disease is very widespread. CABG can be done with or without connecting the patient to heart-lung machine, depending on the kind of blockages and surgeon’s decision.

Several new surgical approaches are being developed, which can potentially reduce the discomfort and complications associated with traditional bypass surgery. These are collectively referred to as being “minimally invasive.” In general, these approaches focus on performing bypass surgery though a very small chest incision and performing bypass surgery while the heart is still beating (ie, without the need for a heart/lung bypass machine).

OPCAB (Off Pump Coronary Artery Bypass)
The bypass surgery done without connecting the patient to of heart-lung machine or pump is called OPCAB.

MIDCAB (Minimally Invasive Direct Coronary Artery Bypass)
is bypass surgery done through a small cut (incision) in the lower part of the sternum (chest bone) only, rather than full cut across it. This type of surgery, which is possible in selected cases only, is associated with a small scar, lesser pain and faster recovery. Alternatively, this surgery can also be done through a small cut on the left side of the chest.

The location and degree of coronary artery blockages are determined before surgery by using a procedure called heart catheterization, or coronary angiogram. This procedure provides an outline, like a road map, of the arteries of the heart.

Factors favoring bypass surgery
Bypass surgery is often recommended over angioplasty when the left main coronary artery is narrowed by more than 50 percent, when angioplasty does not relieve angina, when many arteries are narrowed, or when the heart’s left ventricular pumping function is substantially impaired. Bypass surgery is also preferred over angioplasty in diabetic patients who have two or three vessels involved.

Benefits
Bypass surgery can very effectively relieve angina and can even prolong life in people with severe coronary heart disease, such as those with three-vessel involvement associated with impaired left ventricular pumping function. However, the success of bypass surgery on symptoms and on survival depends upon several factors, including the pattern and extent of arterial narrowing, the general progression of coronary heart disease over time, and the blood vessels used for bypass. In general, bypass surgery is more likely than angioplasty to provide complete revascularisation.

About 95 percent of people who have narrowing of several arteries have improvement or complete relief of their angina immediately after surgery. About 85 to 90 percent of people remain angina-free at one to three years after surgery, and about 75 percent of people remain angina-free or free of major coronary events at five years after surgery. By 10 years, about one-half of all grafted vessels become narrowed or occluded, and by 15 years, about 85 percent of grafted vessels become narrowed or occluded. These late events usually require a second surgery

Recovery from bypass surgery
It usually takes a while to recover from even routine bypass surgery. However, about 70 to 80 percent of people who have this surgery are eventually able to return to work; this is about the same as the percentage of people who are treated medically and are able to return to work. Factors that appear to have a role in a person’s ability to return to work are the presence or absence of angina after surgery, employment status before surgery and income, the function of the heart’s left ventricle, and age.

Catheter Ablation (RFA)

Provided by Escorts Heart Institute
Brought to you by Healthbase

Catheter ablation has revolutionized the management of patients with certain heart rhythm disorders. Having evolved from arrhythmia surgery, catheter ablation was initially performed using high voltage direct current (DC); however, over the last decade, radio frequency current has supplanted DC as the energy source of choice and has made catheter ablation a first-line therapy for many rhythm disorders. It is an alternative to life-long drug therapy or surgery.

The procedure is done in a special room, called an electrophysiology (EP) lab, by doctors trained in the study and treatment of heart rhythms. Long, flexible wires, called catheters, are inserted into the veins of the leg, arm, and neck (and possibly into arteries in the leg) and positioned in the heart. Through these catheters, the doctor can record electrical signals that come from different parts of the heart. This is similar to an ECG, which records electrical activity from the body’s surface.

With, a special catheter, the area of the abnormality is located inside the heart. The catheter is placed at this area and, by delivering either electrical current or heat from radio frequency waves; the defective heart tissue is destroyed. This eliminates the source of the abnormal heart rhythm or extra pathways.

A catheter ablation can take several hours and does involve some risks. However, the doctor recommending this procedure believes these risks are small compared to the potential benefit for you. Your doctor will discuss this with you and answer any questions you have.
