Despite the high number of mortality and morbidity that Filipinos experience first-hand, people are still in the dark when it comes to concerns related to cardiovascular disease. For instance, most people would go see a heart doctor or a cardiologist if they show sudden spikes in blood pressure readings. Physiologically speaking though, hypertensive disorders would fall more into the nephrologists’ (kidney specialists) side of the court. Hypertension can potentially cause problems in the heart in chronic cases because the heart has to work against an increasingly steep pressure gradient, but in the end, the heart pathology is a mere secondary effect and hypertension is rarely borne out of a cardiomyopathologic etiology.
Most people would know that the heart is the pump that sends out oxygenated blood from the lungs to the peripheral structures of the body – i.e. everything else. All structures in the body need nourishment from the blood and the heart itself is no exception. We’ve been hearing the word atherosclerosis a lot lately because it has become one of the more epidemiologically-abundant medical phenomena of our time. As medicine improves and as the life span increases, we’re now seeing how the body reacts to a prolonged high-fat and high-cholesterol diet. Atherosclerosis is the narrowing of blood vessels due to the formation of plaques on the surface of blood vessels. Narrowed blood vessels easily translates to less oxygenation and as if that wasn’t bad enough, the plaques could rupture and cause the blood to clot. This clot could potentially case myocardial infarction or cardiac ischemia. Cardiac cell death can lead to many bad things for the patient – the most grave of course is this condition we call death.
My family has a strong history of heart disease. Atherosclerosis doesn’t limit you to dying of a simple heart attack. The plaques could also break off and cause a stroke in some other part of the body – the worst case scenarios would be the brain and the lungs.
Atherosclerosis may or may not present with symptoms. My Dad had a 95% obstructed artery, but he never experienced chest pains. An electrocardiomyogram showed that his heart was already exhibiting arrhythmia and could have had a heart attack any moment. Fortunately, he was seen by a competent doctor and ablation was done via percutaneous transfemoral coronary angioplasty.
There is plenty to learn about our hearts and how we should take care of it. Of course, I can’t expect everyone to just pick up Harrisson’s Internal Medicine or Netter’s Atlas of Anatomy all of a sudden. It’s a good thing that there are non-threatening, well-written and informative websites out there that discusses the ins and outs of medical conditions.
