If a lack of oxygen hurts and damages your heart muscle, then how bad is it to hold your breath?

Depends. In general a person can not hold their breath long enough to cause heart damage because1: a neurally mediated reflex triggered by the buildup of carbon dioxide is present and will override the breath hold and 2: the duration of time absent complete oxygen required to damage heart muscle is 15-30 minutes.

If my anemia has gone undiagnosed 2 years or more could irrepairable damage have been done to my oxygen deprived heart muscle?

Unlikely. Anemia often produces symptoms before it can cause anyorgan damage. heart is quite sensitive to low oxygen and will produce symptoms of pain in the chest called angina which comes on physical strain and goes away on rest. Unless you have such symptoms of angina you have not risked your heart for any damage. What is your hemoglobin(HB) level? If it is >8 grams, you are not going to have any damage. Read more...

I know that inhaled diesel exhaust particles that get deep into the lungs have been shown to trigger episodes of reduced oxygen supply to the heart muscle. Is this something that will simply be short term only while exposed or will it be permanent?

Pollution. Such inhalation affects the lungs primarily and would not be expected to cause permanent heart damage once you remove yourself from this type of air pollution. However chronic low oxygenation of the blood does in time affect heart function by creating strain on the right ventricle. Hopefully you will avoid this type of pollution. Read more...

Would angina usually hurt where the heart muscle is in the chest? My pain is a little higher than the hearts main cetre and doesn't go to the left

Probably no angina . Ischemic heart chest pain usually retrosternal pressure irradiating to the left shoulder or arm worsening with activities and improving with rest. If above test were negative you do not have coronary artery disease. R/o chest wall pain and acid reflux. Follow up with your doctor. Read more...

I am 47 years, I ask. Does installing pacemaker help to improving my heart muscle, my e.F is 32%. Thanks?

Depends. If the disease is in the muscle, installing a pacer will help if and only if there's a problem getting the atrial kick to the ventricles at the right time. Pacers are great for the right patients, but if the problem is a weak muscle in itself, don't expect benefit. Good luck. Read more...

Can multiple system atrophy affect the heart muscle?

Unfortunately yes. As MSA progresses, every muscle in the body eventually gets affected by the degeneration of the autonomic nerves & other derangements which cannot be compensated for anymore by the "voluntary" nervous system. I have a patient who is likely going through his last stages & it is a relentless disease process for which he now refuses any & all interventions to help him with breathing or swallowing.

I went to the cardiologist today and was told I have a thickening of the heart muscle. Tell me straight how dangerous is this?

Depends. The greater the degree of thickness the worse the prognosis. More importantly the thickening of the heart indicates poor blood pressure controll over a long period of time.The longer this goes on the worse the pronosis. Pts can develope heart failure and arrythmias. Strict blood pressure controll is essential (130/80 or less). Read more...
