Well from your description, the fact that you already hypertensiven, family history of cardiovascular disorder and you are presenting with the above mentioned symptoms is strongly suggestive of heart failure
(probably at an earlier stage). Angina pectoris
is usually significantly associated to stabbing or throbbing pain
on left side of chest which could be during an effort (stable angina) or at rest (unstable angina
). During efforts, you could develop breathless, fatigue and other symptoms such as lightheadedness
+ palpitation etc. If you do not have a left side chest pain then it is most unlikely going to be angina.
There are other possible causes of your symptoms like anemia ( of any origin), asthma (will have other pathognomic symptoms), chest infections (other signs of infections must be generally be present), overweight, ischemic heart diseases (already mentioned= angina) etc.
What to do now? Meet a cardiologist for complete clinical, laboratory and imagery evaluation to determine your disease and the cause, then provide appropriate treatment.
Your antihypertensive medications should be checked too before increasing the dosage as might also be the cause. Do discuss with your doctor.
Hope this helps
