What is Cardiovascular Disease


Cardiovascular disease involves abnormalities of the heart and blood vessels. Coronary heart disease is the most common condition and is the leading cause of death in the United States for both men and women.

The lifetime risk for developing significant cardiovascular disease is greater than the likelihood of developing cancer. Your heart is a muscular pump that requires heart arteries to supply oxygen-rich blood to keep it going.

Coronary heart disease occurs when these blood vessels become narrowed due to a buildup of plaque. The plaque is made up of cholesterol and other substances. This process is called atherosclerosis.

Atherosclerosis occurs over a lifetime, and is influenced by risk factors. Some risk factors can't be changed, however, others can be altered through healthy lifestyle choices and medications if needed. Symptoms of coronary heart disease occur when the heart muscle does not get enough oxygen.

Some describe this as chest pressure or chest pain that starts over the left chest and can radiate or travel to the left arm, left jaw, back, or sometimes to the right chest. Some patients do not have any chest pain or pressure symptoms, but instead have intense shortness of breath or epigastric discomfort that can feel like a bad heartburn. Breathlessness, nausea, vomiting, or sweats can also sometimes be associated. These symptoms are called angina.

There are many treatments for angina, including medications, angioplasty and stents, and bypass surgery. Aggressive risk factor modification is part of every treatment plan. Coronary heart disease can have serious complications, including heart attacks and even sudden death. Fortunately, developing significant coronary heart disease is largely preventable. Early prevention is best, but you can still improve how you'll do no matter how old you are by reducing your risk factors.

One study found that 50-year-old people who had not already developed significant cardiovascular disease and didn't have major risk factors reduced their lifetime risk for developing significant cardiovascular disease, and they lived longer. Continue on through this section to learn more..

A-FIB VERSUS JUNCTIONAL RHYTHMS

. ATRIAL FIBRILLATION: On your rhythm strip, the two most important characteristics are: . 1) A rhythm that’s IRREGULARLY irregular (meaning there’s no way to predict the next beat) 2) No discernible P waves . In fact, if you notice an irregularly irregular rhythm and you’re having to convince yourself that you see P waves... it’s probably A-fib (multifocal atrial arrhythmias like WAP/MAT could fit the differential) . *In my opinion: Don’t get caught up in using fibrillation waves as an absolute criteria. Very fine A-fib can sometimes produce a near isoelectric line between beats. . JUNCTIONAL RHYTHMS: The pacemaker cells surrounding the AV junction are capable of initiating regular impulses but at a slightly slower natural rate than their sinus and atrial superiors. The heart is built this way so that when the pacemaker cells with the fastest intrinsic rates are in action, those below are suppressed and function primarily to pass along the impulse from above. . For these reasons, we s...

What is The Cardiac Cycle ?

The cardiac cycle refers to the sequence of events that occur and repeat with each heartbeat. It can be divided into two main stages: Systole and diastole, each of which is divided into several small steps When systole and diastole are not specified otherwise refers to ventricular contraction and relaxation Respectively, Reminder Blood flows from low to low pressure Compression increases the pressure in a Chamber, while relaxation reduces the pressure. When the AVT valves open the anterior pressures are higher than the ventricular pressures and Off when the pressure gradient is reversed. Similarly, Semiluna valves open when ventricular pressure exceeds submerged /, pulmonary pressure And stop. If the opposite is true, The cycle was started by firing shots at the SA node, which encouraged the atria to lower . Learn here Atrial Fibrillation Treatment It is represented by p-waves in the ECG Shortly after the onset of the P-wave atrial contraction begins and increases the ...
