Heart health Check up. Heart issues yet!

I have had cholesterol issues since my 40s but initially i managed it with statin and lately i have been managing it through diet and lifestyle and was successfully in managing it except last 6 months my triglycerides skyrocketed out of nowhere to 400 again took statin and fenaftibrate and cholesterol ldl last i checked was 230+ triglycerides below 180 and i have never had a ecg echo or any of the advance test except had a stress treadmill that too 15 years back , from last two years after second wave i have started yo feel weak not too much though , i want to consult a cardiologist should i get some advance heart health tests done beforehand for the ease of consultation i might have blood pressure issue too , never checked it regularly but whenever someone took the reading it was always above 140/80 thats why i am a little worried and i have a desk job (sedentary lifestyle) , also none in my blood related family had heart issues yet
