Health: Foods That Fight Inflammation (Harvard)

ATHEROSCLEROSIS: STRESS, LACK OF SLEEP & EXERCISE AND POOR DIET RAISE RISKS

Swirski acknowledged that “there is no question” that genetics play a role in cardiovascular health, but in the last several years, four risk factors — stress, sleep interruption or fragmentation, diet, and sedentary lifestyle — have been clearly identified as contributing to atherosclerosis, commonly referred to as hardening of the arteries, which can lead to a variety of complications, including death.

DR. C’S JOURNAL: WHAT IS VALVULAR HEART DISEASE?

I continue to be amazed by-and grateful for -the astounding collection of miracles that is the human body. Each element is durable if properly maintained and potentially provides us with a long and healthy life. The heart Valves are a part this wonderful orchestra, opening and closing about 2 billion times in a full lifetime.

It is possible to visually appreciate our heart and it’s valves, but millions of other microscopic-nanoscopic-little protein machines are also opening, closing, twisting and folding anonymously, allowing us to live and move.

Now is a particularly good time to talk about the heart valves because imaging devices are available to detect, and surgical techniques are at hand to treat, the common problems that develop in the course of optimally guiding our blood through the heart, into 2 separate circuits, the pulmonary, and the systemic. Life can be defined as an island of order in a sea of chaos. Energy is required to allow this island to fend off dissolution. The energy is used to continually maintain the integrity of our cells, the island in this metaphor, and keep entropy at bay.  Myriads of biochemical mechanisms direct this repair. Sleep, diet, and exercise aid in the mending.

We use our bodies in the daytime, and at night switch to a cleansing and repairing function, sleep.  Diet, and our resident microbiome, provide the materials for this restoration. Exercise helps utilize excessive nutrients, and directs our metabolism towards regeneration and repair.

Some valvular problems are present at birth because of defective development. Bicuspid aortic valves and mitral prolapse are examples. Hypertension places a strain on the entire system. Type two diabetes can cause inflammation and abnormal deposits in the valves. A variety of biochemical pathways active during the formation of the heart can go awry and fail to maintain the neatly layered deposits of collagen, proteoglycans and elastic tissue that forms the basis of the valves, and the endothelial cells that line them.

Tobacco smoke, which harms in so many other ways, can also damage the heart valves, as can infections, which sometimes grow on the heart valves themselves. Symptoms of heart valve disease include abnormal sounds that your doctor can hear, or the the presence of fatigue, shortness of breath, swelling of the ankles, and dizziness, which are common symptoms of cardiac malfunction. Unusual chest pains, particularly with mitral prolapse, and irregular heartbeat can also be present.

Replacement of some valves via a catheter inserted in an artery is one of the recent advances in treatment of Valvular heart disease.

Ultrasound is particularly useful in diagnosing valvular heart disease, but a whole cafeteria of diagnostic tests are available to doctors these days.
Please refer to the following Mayo clinic article for more information.

Tachycardia: Types, Causes & Symptoms (Mayo Clinic)

Tachycardia is the medical term for a heart rate over 100 beats per minute. There are many heart rhythm disorders (arrhythmias) that can cause tachycardia.

Types of tachycardia

There are many different types of tachycardia. They’re grouped according to the part of the heart responsible for the fast heart rate and cause of the abnormally fast heartbeat. Common types of tachycardia include:

  • Atrial fibrillation. Atrial fibrillation is a rapid heart rate caused by chaotic, irregular electrical impulses in the upper chambers of the heart (atria). These signals result in rapid, uncoordinated, weak contractions of the atria.Atrial fibrillation may be temporary, but some episodes won’t end unless treated. Atrial fibrillation is the most common type of tachycardia.
  • Atrial flutter. In atrial flutter, the heart’s atria beat very fast but at a regular rate. The fast rate results in weak contractions of the atria. Atrial flutter is caused by irregular circuitry within the atria.Episodes of atrial flutter may go away themselves or may require treatment. People who have atrial flutter also often have atrial fibrillation at other times.
  • Supraventricular tachycardia (SVT). Supraventricular tachycardia is an abnormally fast heartbeat that starts somewhere above the lower chambers of the heart (ventricles). It’s caused by abnormal circuitry in the heart that is usually present at birth and creates a loop of overlapping signals.
  • Ventricular tachycardia. Ventricular tachycardia is a rapid heart rate that starts with abnormal electrical signals in the lower chambers of the heart (ventricles). The rapid heart rate doesn’t allow the ventricles to fill and contract efficiently to pump enough blood to the body.Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. But episodes lasting more than a few seconds can become a life-threatening medical emergency.
  • Ventricular fibrillation. Ventricular fibrillation occurs when rapid, chaotic electrical impulses cause the lower heart chambers (ventricles) to quiver instead of pumping necessary blood to the body. This can be deadly if the heart isn’t restored to a normal rhythm within minutes with an electric shock to the heart (defibrillation).Ventricular fibrillation may occur during or after a heart attack. Most people who have ventricular fibrillation have an underlying heart disease or have experienced serious trauma, such as being struck by lightning.

INFOGRAPHIC: POOR ORAL HEALTH LEADS TO CHRONIC AND SYSTEMIC DISEASE

Good oral health leads to benefits beyond a healthy mouth

People today want to be more in control of their own health and are more attuned to getting the support and information they need online, from apps, and from connected products. Yet there are gaps in both their knowledge and daily commitment to good oral hygiene, and they need help along the way. Depending on lifestage, patient’s oral health concerns can evolve from plaque removal and aesthetics to larger concerns around gum health and disease. Too often, by the time they begin thinking about gum health, it’s too late. Multiple studies have revealed linkages between periodontal diseases and certain systemic diseases, such as diabetesheart disease and kidney disease [4][5][6].

Prevention is key. Along with professional deep cleaning, good daily brushing and interdental cleaning are critical. It’s also important for patients to have regular conversations with their dentist about oral health issues and the linkage to their overall health.

Heart Failure: ‘What It Is & How To Treat It’ (Video)

The heart is a hero. It works relentlessly to deliver oxygen and nutrients to the body. But just like all heroes, sometimes it gets tired, and can’t do its job as well. This is called heart failure – the inability for the heart to pump enough blood and oxygen to the lungs and rest of the body. In this video, Northwestern Medicine cardiologists Clyde W. Yancy, MD, MSc and Jane E. Wilcox, MD, MSc explain what heart failure is and the integrated and collaborative approach used to diagnose, stage and treat heart failure at Northwestern Medicine.

YALE MEDICINE: ‘WHAT CAUSES HEART FAILURE?’

The heart is a muscle and it’s main job is to pump blood but certain things can cause that muscle to fail. There are genetic reasons, there are reasons related to valve disease, and there’s a viral infection that affects the heart called myocarditis.

The most common cause of heart failure is a heart attack. Fatty plaque builds up in the blood vessel that supplies the heart itself and unless that blood vessel is opened up immediately that muscle will die. The rest of the muscle that’s not dead anymore has to do extra to keep on pumping the blood and overtime it cannot keep and that’s when heart failure develops.
