This means:
“A widely used blood-pressure medication has been associated in research with a higher risk of sudden cardiac arrest.”
Breakdown
“Popular blood pressure drug” = a commonly prescribed medication for hypertension.
“Linked to” = associated with an increased risk in a study; it does not necessarily mean the medication causes cardiac arrest.
“Increased cardiac arrest risk” = suggests a higher likelihood of sudden cardiac arrest, a medical emergency in which the heart suddenly stops pumping effectively.
What the headline may be referring to
One widely reported 2019 study examined nifedipine and amlodipine, two calcium-channel blockers. It found that high-dose nifedipine (60 mg/day or more) was associated with a higher risk of out-of-hospital cardiac arrest, while low-dose nifedipine and amlodipine did not show the same association. The researchers specifically cautioned that the findings needed to be replicated before doctors or patients changed treatment.

So the headline shouldn’t be interpreted as “this drug causes cardiac arrest” or as advice to stop taking it.
A more accurate version:
“Study finds a possible association between high-dose nifedipine and sudden cardiac arrest—what patients should know.”
