Treatment for hypertension, arrhythmias, and angina pectoris may include:

Proton pump inhibitors (PPIs) are primarily used to reduce stomach acid production and treat conditions like gastroesophageal reflux disease (GERD) and peptic ulcers. They do not have any role in managing cardiovascular conditions such as hypertension, arrhythmias, or angina pectoris, making them an inappropriate choice for this question.

HMG-CoA reductase inhibitors, commonly known as statins, are primarily used to lower cholesterol levels in the blood. While they can help reduce the risk of cardiovascular events, they do not directly treat hypertension, arrhythmias, or angina pectoris, thus making them irrelevant for this specific question.

Benzodiazepines are medications primarily used for treating anxiety, insomnia, and seizures. They do not have a direct therapeutic effect on cardiovascular conditions such as hypertension, arrhythmias, or angina pectoris, thereby rendering them unsuitable for this context.
