Cardiologist

In the cardiovascular arena, hundreds of thousands of patients are treated by interventional cardiologists, whereas in the past these people would have been treated by surgeons. The surgeons, to offset the loss of some patients, take on more difficult procedures which over time become routine in nature. Thus, more patients can be successfully treated and the marketplace expands. 

Clinical evaluation is underway to test transvenous electrodes. Transvenous leads permit pacemakers to be implanted under local anesthesia while the patient is awake, greatly reducing recovery time and risk. As of 1996, the generation of implantable defibrillators requires a thoracotomy, a surgical opening of the chest, in order to attach electrodes to the outside of the heart. Transvenous electrodes would allow cardiologists to perform pacemaker procedures without a hospital or the use of general anesthesia. 

There are a few absolute contraindications for deep peeling, mainly physical or mental instability. During pregnancy and lactation any cosmetic intervention is considered undesirable. All patients are required to perform electrocardiogram and complete blood count prior to the procedure. Any heart disease requires special precautions and it is always recommended to work in cooperation with the patient s cardiologist. 

Studies in chemistry or any realm of science commonly consist of a series of directed examinations of parts of nature s realm called systems. A system is an identifiable fragment of the world that is recognizable and that has attributes that one can identify in terms of form and/or function. We can give examples at any level of size and complexity and in essentially any context. Indeed, a dog is a system at a pet show whereas the human heart is a system to the cardiologist a tumor cell is a system to the cancer specialist a star or planet or galaxy is a system to an astronomer a molecule or a collection of molecules is a system to a chemist and an atom or group of atoms is a system to a physicist. A system is, then, whatever we focus our attention upon for study and examination.

Practitioners must have a good understanding of cardiovascular physiology to diagnose, treat, and monitor circulatory problems in critically ill patients. Eugene Braunwald, a renowned cardiologist, described the interrelationships between the major hemodynamic variables (Fig. 10-1).1 These variables include arterial blood pressure, cardiac output (CO), systemic vascular resistance (SVR), heart rate (HR), stroke volume (SV), left ventricular size, afterload, myocardial contractility, and preload. While an oversim-... 

Normal cardiac contraction depends on the conduction of electrical impulses through the myocardium in a highly coordinated fashion. Any abnormality of the initiation or propagation of the impulse is referred to as an arrhythmia. These disorders are the most common clinical problem encountered by a cardiologist. There is a wide range of types of arrhythmias with multiple etiologies and a variety of symptoms. In this section, two types of cardiac tachyarrhythmias are discussed. The most common treatment for these conditions is drug therapy. 

Although the delineation of panic disorder as a unique diagnostic entity is a relatively recent development, references to what would today be known as panic attacks commonly appeared in the annals of medical and psychiatric literature. For example, cardiologists, who frequently encounter patients with panic disorder due to the dramatic presentation of cardiac symptoms in association with panic, have numerous terms for panic including cardiac neurosis, DaCosta s syndrome, soldier s heart, and neurocirculatory asthenia. 

Hospital specialists will readily start to prescribe a new product if they are convinced of its safety and efficacy, provided it is for use in their own specialty. They are much less ready to try a new compound if it is outside their area of expertise. A cardiologist, for example, would be much less likely to try a new anti-ulcer drug than an antihypertensive until first discussing it with a gastroenterologist colleague. 

The publication of the 4S study in 1994 transformed the debate. The study demonstrated unequivocally that cholesterol, lowered total as well as cardiovascular mortality with no increased risk of cancer. Cardiologists, who as a group, were previously sceptical of the value of cholesterol lowering, became strong advocates of a change in public health policy. As Professor Oliver wrote in the British Medical Journal in 1995 Lower patient s cholesterol now - trial evidence shows clear benefits from secondary prevention. As noted previously, UK physicians are remarkably conservative, and largely follow the principles of evidence-based medicine. When the evidence is presented to them... 

Potential advantages of the Impella compared to the TandemHeart include miniature size (13 F versus 17 F), ease of insertion, maintenance of limb perfusion, and low bleeding rate. Retrograde insertion of the Impella is a technique familiar to most cardiologists. However, the Impella 2.5 can generate only 2.5 1 of cardiac output and hence is suitable for patients with some intrinsic left ventricular function. The TandemHeart, however, can generate an output of 3.5 1/min and can almost completely replace left ventricle function. 

Despite efforts such as revascularization to halt the progression to ischemic heart failure, ventricular remodeling is still a growing danger. Efforts to treat severely failing hearts refractory to medical therapy have included heart transplantation and mechanical ventricular assistance [1]. Until recently, cardiologists believed that beyond revascularization and medical therapy, the process of ischemic heart failure was irreversible because the heart lacked the capacity to renew itself. 

The data recorded by these novel defibrillators can be downloaded in the office of the general and heart failure cardiologist with a simple device that will provide a printout of a heart failure profile, which can be used in the assessment of the patient at that clinic visit. This has been demonstrated by the...

In the case of abnormal EKGs at baseline, the use of a TCA, as well as potential risks and benefits, needs to be carefully reevaluated. In addition, a family history of premature cardiac problems or a personal history of cardiac disease, especially structural and conduction abnormalities, should warrant consultation with a pediatric cardiologist before starting medications. Parents and patients should be aware of the potential risk for...

Cynthia approaches the cardiologists in her clinic with an idea that she could start a heart failure clinic to provide additional education and monitoring for these patients. While the physicians would oversee the clinic, she could conduct monthly educational seminars about heart failure for patients, order and assess laboratory tests, and order medications and adjust dosages under physician-approved protocols.
